catalyst: azobisisobutyronitrile in neat (no solvent)
equimolar amts. of the alkyne and Me3SnH were heated at 70°C under Ar in the presence of a catalytic amt. of AIBN for 3-4 h (IR and (1)H NMR monitoring); PhCH=C(SnMe3)2 to Ph(Me3Sn)C=CHSnMe3 ratio 95:5, total yield 81percent; the reaction mixt. was distilled under reduced pressure (b.p. 86°C/0.005 mm Hg); elem. anal. for the isomeric mixt., isomers were not sepd.;
