Diphenyl(trimethylstannyl)phosphine adds to alkynes (both terminal and non-terminal) and allenes under free radical conditions. The former reaction occurs regiospecifically with preferential formation of E-isomers, the latter regioselectively. Product identification was based on NMR spectroscopic data. With one exception, addition to alkenes was not observed.

The novel germanium-containing alkylidenecomplexes of molybdenum R3Ge–CHMo(NAr)(OCMe2CF3)2 (Ar = 2,6-i-Pr2C6H3; R = Me, Ph) have been prepared by the reaction of organogermanium vinyl reagents R3 GeCHCH2 with known alkylidene compounds Alkyl–CHMo(NAr)(OCMe2CF3)2 (Alkyl = But, PhMe2C). The titled compounds were isolated as crystalline solids and characterized by elemental analysis, 1H NMR, 13C NMR
