Trifluoro(phenyl)silane reacts with aliphatic alcohols under reflux. The reaction involves not only Si-F bond cleavage to form ethoxyfluoro(phenyl)silanes, but also C-Si bond cleavage to form benzene and alkoxyfluoro- and tetraalkoxysilanes. The formation of the latter products was proved by 19F and 29Si NMR spectroscopy and also by model disproportionation reactions of trifluoro(phenyl)silane with trimethoxy-(phenyl)-
三氟(苯基)硅烷在回流下与脂肪醇反应。该反应不仅涉及Si-F键裂解形成乙氧基氟(苯基)硅烷,而且涉及C-Si键裂解形成苯以及烷氧基氟-和四烷氧基硅烷。后一种产物的形成通过19 F和29 Si NMR光谱以及三氟(苯基)硅烷与三甲氧基-(苯基)-,四甲氧基-或四乙氧基硅烷的模型歧化反应证明。
