U. Schubert et al., TRANSITION-METAL SILYL COMPLEXES, .52. FO RMATION OF COPPER SILYL ANDSTANNYL COMPLEXES BY REACTION OF [PH3PCUH]6 WITH HER3 (E=SI, SN), Chemische Berichte, 127(11), 1994, pp. 2189-2190
[Ph3PCuH]6 was used as a source for the Ph3PCu fragment to prepare cop
per stannyl and silyl complexes. Reaction of [Ph3PCuH]6 with HSnPh3, H
SiPh3 or HSiClPh2, respectively, and two equivalents of PPh3 yielded t
he complexes (Ph3P)3CuER3 (ER3 = SnPh3, SiPh3, SiClPh2).
