Reactions of peralkyl organotin and organomercury compounds with di- and triarylmethyl salts

Abstract

1. In the reactions of peralkyl organotin compounds containing a primary β-H atom with diarylmethyl salts, β-elimination and substitution occur simultaneously. 2. The proportion of the β-elimination product in the reaction mixture increases as the stability of the diarylmethyl cation increases. 3. The reactions of dipropylmercury with diarylmethyl salts, like those of peralkyl organotin compounds with triarylmethyl salts, result in exclusive β-elimination, irrespective of the stability of the corresponding cation.
