Abstract

Abstract Reaction of mesityllithium with SnCl 4 (2: 1) gives (mesityl) 2 SnCl 2, while the corresponding reaction using mesitylmagnesium bromide gives a mixture of halogenato- products (mesityl) 2 SnCl 2,(mesityl) 2 SnBr 2 and (mesityl) 2 SnClBr. Reaction of this latter mixture with SnCl 4 (1: 1) gives the full range of (mesityl) SnX n Y 3-n (X Cl, Y Br). In contrast, the more sterically demanding carbanion source 2, 4, 6-i Pr 3 C 6 H 2 Li reacts ...
