Abstract
The invention discloses triphenyltin o-phenyl dioxy acetate. Triphenyltin o-phenyl dioxy acetate is a complex with a structural formula (I) shown in the specification, wherein Ph is phenyl. The invention also discloses a preparation method for the complex and applications in biological weeding activity.
Description
Technical field
The present invention relates to a kind of triphenyltin adjacent benzene dioxy acetic ester and preparation method thereof, and the application of the adjacent benzene dioxy acetic ester of this triphenyltin in plant growth regulating.
Background technology
In agriculture weeding, use a kind of weedicide or its composition for a long time, in a large number, weeds can develop immunity to drugs, and therefore, weedicide needs continuous innovation.People are in order to find the good herbicidal compound of high reactivity, highly selective and Environmental compatibility, and one of fruitful approach utilizes the activated compound of tool for guide's developing new drug thing.As everyone knows, since discovery 2,4-dichlorphenoxyacetic acid has efficiently, after the weeding of highly selective and biological regulation effect, phenoxy carboxylic acid herbicides is because structure is simple, activity is high, cost is low, is the class weedicide that output is maximum, usable floor area is the widest always.
Phenoxy acetic acid is not only widely used, and structure is special, different from general phenylformic acid, lipid acid, its alkoxyl group with rigidity phenyl ring, flexibility and the carboxyl of strong coordination, there is the feature of the organometallic complex of the coordination mode flexible and changeable with metal and the changeable formation different structure of sterie configuration, the new compound with novel structure and property can be constructed.
Organotin and derivative thereof not only have good biological activity, are used as desinsection, sterilization and cancer therapy drug, and antifouling paint, wood preservation etc.Some organo-tin compounds, also have the weeding activity being better than or being equivalent to 2,4 dichlorophenoxyacetic acid.Their low phytotoxicities, general low to the toxicity of non-target tissues, in environment under light, heat and biological action, easily can be transformed into the less compound of toxicity quickly, finally be degraded into nontoxic tindioxide residue, have desinsection, the multiple effect of sterilization concurrently as weedicide, demonstrate good Development volue.Therefore, with phenoxy acetic acid and organo-tin compound for precursor, organotin phenoxy acetic acid ester is formed with the key effect that becomes of tin by carboxyl, or form title complex by the coordination of carbonyl and tin, the compounds two classes with weeding activity is integrated, seek that drug effect is better, selectivity be better, the weedicide new variety of use safety, significant.
Document (Chinese Journal of Inorganic Chemistry, 2006,22:656-660) is reported, the synthetic method of dialkyl tin Chlorlacetic Acid ester.
Document (organic chemistry, 2006,11:1571-1575) report, series of new is containing aryloxyacetic acid ester group triadimefon compound, the weeding activity test result of this series compound shows, substituting groups different on phenyl ring has obvious impact to weeding activity.
Document (chemical journal, 1995,53:1034-1040) report, the synthetic method of mixed trialkylated tin derivative methyldicyclohexyl tin (replacement) phenoxy acetic acid ester and biological activity, research shows, these compounds, except there being good acaricidal activity, also have certain sterilization, weeding and Plant Hormone Action.
Document (Chinese Journal of Inorganic Chemistry, 2010,26:1507-1510) is reported, the synthetic method of tri-n-butyl tin 2,4 dichlorophenoxyacetic acid ester and its structure.
Document (chemical research and application, 2010,22:926-929) is reported, the synthetic method of siliceous dialkyl tin phenoxy acetic acid title complex.
Document (organic chemistry, 1991,11:82-87) is reported, the synthetic method of Tricyclohexyltin aromatoxyacetate and kill mite and the effect to plant-growth regulator.
Document (JournalofOrganometallicChemistry, 2014,758:19-24) is reported, the synthetic method of di-n-butyl tin isophthalic dioxy acetic ester.
Document (SCI, 1991,12:1186-1189) is reported, the synthesis of tributyl tin hydrocarbon fluoroacetate and weeding activity, and the weeding activity of this compounds is better than or close to weedicide 2,4 dichlorophenoxyacetic acid.
Document (chemical journal, 1995,53:721-728) is reported, mixing tributyl tin carboxylicesters is to the weeding activity of the test materialss such as oat, barnyard grass, lady's-grass, rape, clover, three-coloured amaranth, and part of compounds has good inhibition.
Mixed trialkylated tin derivative pesticide disclosed in Chinese patent CN1097546A has very strong sterilization, desinsection, kills the two or more biological activity such as mite and weeding.
US Patent No. 3723089 discloses the plant growth regulation of a kind of organo-tin compound to plant such as leaf mustard, lamb's-quarters, lady's-grass, corn, wheat, cotton, peas.
US Patent No. 4260552 discloses the weeding activity of a series of polysubstituted organo-tin compound to plant such as lamb's-quarters, thorn apple, morning glory, lady's-grass, paddy green bristlegrass and barnyard grasses, and the growth inhibition ratio of most compounds to tested plant reaches 100%.
The experiment proved that material plant to growth regulating effect based on trialkylated tin aryloxyacetic acid ester compound, the present invention selects the organotin of fentin hydroxide, adjacent benzene two fluoroacetic acid is part, react under certain condition, synthesis obtains the compound stronger to the growth regulating effect of purslane, Amaranthus retroflexus, Semen Cassiae, thorn amaranth, red roundleaf three-coloured amaranth, clover, provides new approach for developing new plant-growth regulator.
Summary of the invention
The first object of the present invention there is provided a kind of triphenyltin adjacent benzene dioxy acetic ester.
The second object of the present invention is to provide the preparation method of above-mentioned triphenyltin adjacent benzene dioxy acetic ester.
The third object of the present invention is to provide the application of the adjacent benzene dioxy acetic ester of above-mentioned triphenyltin in plant-growth regulator.
As a kind of triphenyltin adjacent benzene dioxy acetic ester of first aspect present invention, the compound for following structural formula (I):
Wherein Ph represents phenyl.
Triphenyltin of the present invention adjacent benzene dioxy acetic ester is through ultimate analysis, Infrared spectroscopy and nuclear magnetic resonance spectrum structural analysis, and result is as follows:
