Group IB Organometallic chemistry. XV. Arylcopper compounds ArnCun as intermediates in organometallic synthesis. One-step synthesis of triorganotin halides of the type Ar3SnX and Ar3-nRnSnX
article
A new method for the one-step preparation of triorganotin halides is described. Triphenyltin halides are synthesized via the reaction of pure phenylcopper with SnX4 or with Ph2SnX2. Me2NCH2, Me2N and OMe-substituted phenylcopper react with Me2(or Ph2)SnBr2 to give novel (substituted-phenyl)-diorganotin bromides in high yields. The selective arylation of tin halides by organocopper compounds is based upon the low reactivity of RCu towards the SnX bond in triorganotin halides. The selectivity of the arylation by the corresponding phenyllithium derivatives is connected with intra- or inter-molecular SnN (or O) coordination and/or of steric factors exerted by substituents ortho to the SnC(phenyl) bond. © 1975.
