Abstract

1376438 Piperidine derivatives CIBAGEIGY AG 30 Nov 1972 [30 Nov -1971] 55486/71 Heading C2C [Also in Division C3] Novel piperidine derivatives having the general formula wherein A is -CH 2 -, -CH 2 -CH 2 - or R 1 and R 2 are (C 1 -C 6 ) alkyl groups or 1- methylcyclohexyl or α,α-dimethylbenzyl radicals; R 3 and R 4 are (C 1 -C 12 ) alkyl groups, or together with the intermediate carbon atom form a (C 5 -C 8 ) saturated alicyclio residue or a group of the formula and n is 0 or 1, are prepared by reacting a compound of the formula with either (a) an acid halide of the formula wherein Y is halogen, in the presence of a halogen-acid binding substance, (b) an ester of the formula wherein R is a (C 1 -C 6 ) alkyl group, in the presence of a transesterification catalyst, or (c) a carboxylic acid of the formula in the presence of an esterification catalyst. The novel compounds may be used as stabilizers for polymers.
