J. Ohshita et al., OXIDATIVE COUPLING OF LITHIUM SILENOLATES - FIRST SYNTHESIS OF BIS(ACYL)-SUBSTITUTED POLYSILANES, Organometallics, 15(9), 1996, pp. 2198-2200
Treatment of lithium 2-meistyl-, adamantyl-, and tert-butyl-1,1-bis(tr
imethylsilyl)-1-silen-2-olate with 0.5 equiv of palladium dichloride a
fforded the corresponding coupling products, 1,2-bis(acyl)tetrakis(tri
methylsilyl)disilanes (3a-c), in high yields. The molecular structure
of compound 3b was established by single-crystal X-ray diffraction stu
dy.
