  Photoalkylation of tetracyanobenzene and benzil with (n-Bu)3SnSiMe3 or (n-Bu)3SnSn(n-Bu)3 proceeds via electron transfer. In these reactions, the Sn–C bond of (n-Bu)3SnSiMe3 and (n-Bu)3SnSn(n-Bu)3 is cleaved in preference to the Sn–Si and Sn–Sn bonds. Similar cleavage of the Sn–C bond is also observed in mass spectra of these group 14 organometallic compounds.

  四氰基苯和苯偶酰与（n-Bu）3SnSiMe3或（n-Bu）3SnSn（n-Bu）3的照相烷基化是通过电子转移进行的。在这些反应中，（n-Bu）3SnSiMe3和（n-Bu）3SnSn（n-Bu）3的Sn-C键断裂优先于Sn-Si和Sn-Sn键。在14族有机金属化合物的质谱中，也观察到了类似的Sn-C键断裂。

  Composition comprising a transition metal component and magnesium hydrocarbyl carbonate. Composition can be prepared by reacting suspension of magnesium alcoholate with carbon dioxide to form a magnesium hydrocarbyl carbonate and reacting magnesium hydrocarbyl carbonate with transition metal component. When the suspending liquid comprises an alcohol, the magnesium hydrocarbyl carbonate dissolves and is subsequently precipitated with an antisolvent comprising metal alkyl or transition metal halide. When the suspending liquid is substantially free of alcohol, the magnesium hydrocarbyl carbonate suspension is reacted with metal alkyl and transition metal compound.
