give YC6H4CH2SnR3 for (a) R = n-Bu, Y = H, m-OMe, p-OMe, m-Cl, m-CN, and m-NO2, and (b) R = Me, Y = m-Cl, m-CN, p-CN and m-NO2. These reactions are of special value as preparative procedures in cases in which Grignard or organolithium reagents cannot be used. Allyl chloride and bromide were likewise shown to react with (n-Bu3Sn)2 to give CH2CHCH2SnBu3, but n-BuCl and n-BuBr gave only a trace of n-Bu4Sn
