It has been shown, on the basis of the analysis of CIDNP effects, that allene and (Me3Si)2NH — major products of the photoinduced reaction of Et3SnCH2CHCH2 and (Me3Si)2NBr — result from a radicalpair comprised of CH2CHBrCH2SnEt3 and N(SiMe3)2 free radicals. Allene is formed through the β-cleavage of the short-lived homolytic substitution product Et3SnCH2CBrCH2.

A series of allyl- and β-methallyltin compounds have been prepared by the action of the olefinic Grignard reagent on the appropriate tin halide and their infrared spectra recorded. The compounds prepared include (C2H5)3SnR; (n-C4H9)3SnR; (C6H5)2SnR; (p-CH3C6H4)2SnR; (C2H5)2SnR2; (n-C4H9)2SnR2 (R = allyl); (C2H5)3SnR; (n-C4H9)3SnR′; (C6H5)3SnR′; (p-CH3C6H4)3SnR′ and (n-C4H9)2SnR′2 (R′ = β-methallyl)

Organotin compounds such as allyltrimethyltin, cyclopentadienyl trimethyltin, indenyltrimethyltin etc., react with a wide variety of metal carbonyl halides and other metal carbonyl compounds to afford the corresponding π-enyl metal carbonyl derivatives. In many cases conditions are very mild and yields are high, thus commending the reactions for extensive synthetic applications. The possible mechanisms
