Chemistry:Thioacyl chloride
From HandWiki
In organic chemistry, thioacyl chloride is a functional group of the type RC(S)Cl, where R is an organic substituent. Thioacyl chlorides are analogous to acid chlorides, but much rarer and less robust. The best studied is thiobenzoyl chloride, a purple oil first prepared by chlorination of dithiobenzoic acid with a combination of chlorine and thionyl chloride.[1][2] A more modern preparation employs phosgene as the chlorinating agent,[3] this also generates carbonyl sulfide as a by-product.
PhCS2H + COCl2 → PhC(S)Cl + HCl + COS The most common thioacyl chloride is thiophosgene.
