Y. Taniguchi et al., NOVEL SYNTHESES OF 1,2-DIARYLACETYLENES AND ALPHA-SILYALCOHOLS FROM ACYLSILANES MEDIATED BY YTTERBIUM METAL, Chemistry Letters, (7), 1993, pp. 1165-1168
Aromatic acylsilanes such as benzoyltrimethylsilane react with ytterbi
um metal to give symmetrical 1, 2-diarylacetylenes in good yields. Ali
phatic acylsilanes are reduced with lanthanoid reagents such as Yb met
al and SmI2 to afford alpha-silylalcohols.
