実験手順
A mixture of 3.8 g (0.025 g mole) of methyl phenyl carbonate, 3.83 g (0.025 g mole) of trimethylbromosilane, and 0.09 g of tetra-n-butyl phosphonium bromide in 15 ml of sulfolane was heated at 120° C. in a reaction flask equipped with a reflux condenser. After 16 hours of heating, the reflux condenser was replaced by a distillation head and 2.7 g (65 percent yield) of phenoxytrimethylsilane was distilled at reduced pressure from the reaction mixture at a head temperature of 71° C.-72° C./18 mm Hg.
