Novel Syntheses of 1,2-Diarylacetylenes and α-Silylalcohols from Acylsilanes Mediated by Ytterbium Metal

Taniguchi, Yuki,Fujii, Nobuto,Makioka, Yoshikazu,Takaki, Ken,Fujiwara, Yuzo

, p. 1165 - 1168 (1993)

Aromatic acylsilanes such as benzoyltrimethylsilane react with ytterbium metal to give symmetrical 1,2-diarylacetylenes in good yields.Aliphatic acylsilanes are reduced with lanthanoid reagents as Yb metal and SmI2 to afford α-silylalcohols.
