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

Kinetic studies of the reaction between the organometallic complex [Ru(CO)3(1–5-η-C6H7)]BF4(1) and aryltrimethyl-silanes and -stannanes of the type XC6H4M′Me3(M′= Si or Sn; X = H, 4-NMe2, 4-OMe, 1 -OMe, 4-Me, 4-SMe, 4-F, 4-Cl, 4-Br, 3-F, or 3-CF3) reveal the rate law, rate =k[ Ru][XC6H4M′Me3]. This rate law has been rationalised in terms of a rate-determining electrophilic attack by complex (1) on

To evaluate the suitability of [F-18]perchorylfluoride [F-18]FClO3 as an electrophilic fluorination agent for the preparation of radio-pharmaceuticals, the reactivity non-radioactive FClO3 towards 4-substituted trimethyltin aromatic compounds was studied. Contrary to the expectation, an electrophilic fluorination of the aromatic nucleus did not occur. The reaction of perchlorylfluoride with aromatic trimethylstannyl compounds resulted in the formation of trimethyltin fluoride and the respective destannylated aromatics in variable yields.
