or (VI) by chlorine—lithium exchange, with various alkyl and aryl Grignard reagents
and CuCN·2LiCl provides 1,1-disilylmethylcopper species. Aerobic oxidation affords
acylsilanes in good yields. A very different reactivity between two types of cyanocuprates is observed for the reaction with silyldichloromethyllithium derived from silane
(VIII). In addition to alkylation—cyanation, consecutive butylation—phenylation is
accomplished for compound (VIII). — (KONDO, J.; INOUE, A.; ITO, Y.;
