YieldReaction ConditionsOperation in experiment
59% With chloro-trimethyl-silane; water; In benzene; for 26h;Inert atmosphere; General procedure: A mixtureof methanol (2 mL), distilled water (0.09 g, 5 mmol), and trimethylchlorosilane(0.01 g) was slowly added dropwise to a vigorosuly stirred solution of the appropriate silane (0.01 mol) in methanol (10 mL). Trimethylchlorosilane was used as a sourceof hydrogen chloride. The reaction mixture was stirred for 10 hand allowed to stand for 16 h. Excess methanol was removedin vacuo. Compound 1 (59%) was isolated by distillation; compound2 (67%), by recrystallization from pentane.1,3-Dimethoxy-1,3-dimethyl-1,3-diphenyldisiloxane (1).
