in diethyl ether CF3SnBr3 condensed onto of an etheric soln. of CH3Li, then warmed to room temp. and kept 3 min with stirring, with a large excess of CH3Li; volatile removed and fractionated to remove solvent, the remaining material was identified by NMR;

educts separately condensed into a reactor held at -196°C, then allowed to react for 15 min at room temp., at 10-fold excess of (CH3)2Cd; volatile products were removed and analyzed, identification by NMR;

in diethyl ether at 20°C (3 min);
