Acyl iodides in organic synthesis: VII. Reactions with trialkyl(alkynyl) silanes, -germanes, and -stannanes

Article abstract of DOI:10.1134/S1070428006010040

Reactions of acyl iodides R¹COI (R¹ = Me, Ph) with trialkyl(alkynyl)silanes, -germanes, and stannanes (R²C≡ CMR₃³; M = Si, Ge, Sn) were studied. Acyl iodides reacted with the germanium and tin derivatives with cleavage of the M-C_sp bond and formation of the corresponding trialkyl(iodo)germanes and -stannanes R₃³MI (M = Ge, Sn) and alkynyl ketones R ¹C(O)C≡CR² and R¹C(O)C≡CC(O)R ¹. By contrast, the reaction of acetyl iodide with ethynyl(trimethyl)silane gave only a small amount of 1,2-diiodovinyl(trimethyl) silane as a result of iodine addition at the triple bond. Bis(trimethylsilyl) ethyne failed to react with acetyl iodide. Pleiades Publishing, Inc., 2006.
