A number of organotin compounds with the general formula R n SnY 4‐ n where R = alkyl and aryl, Y = thiolate, carbothiolate, and carboxylate, and n = 0, 1, 2, 3 were cleaved with aqueous hydrochloric acid to give the corresponding organotin chlorides and thiols, carbothiolic acids or carboxylic acids. The organotion salts were also evaluated as thermal stabilizers for PVC, and their efficiency was compared with the nature of the aqueous acid cleavage products. 1
