As. Ali et al., PREPARATION OF CYCLOHEXANE-1,3-DIONE HERBICIDE PRECURSORS BY BIRCH REDUCTION OF 3,5-DIMETHOXYPHENYL-SUBSTITUTED SILANE DERIVATIVES, Australian Journal of Chemistry, 47(6), 1994, pp. 1205-1210
Birch reduction of the silane derivatives (3a-d), prepared from Grigna
rd cross-coupling reactions, afforded the cyclohexane-1,3-dione deriva
tives (5a-d) after acid hydrolysis. Compounds (5a-d) are precursors to
silicon-containing herbicides of the general structure (8).
