Reaction Conditions

Reaction Steps

A 2 liter, 4-necked flask equipped as in Example 1 was charged with 500 g (5.94 mol) of neohexene and 1 ml of a 10% chloroplatinic acid in THF solution. The mixture was heated to reflux (about 42° C.). 805 g (5.94 mol) of methyldichlorosilane was then added dropwise. After the addition of about 70 ml of the silane, the reaction commenced and the temperature in the flask rose to 102° C. as the remainder of the silane was added. The reaction mixture was allowed to cool to room temperature (about 25° C.) after the addition of the silane. Upon completion of the reaction, the remaining volatile components were removed at reduced pressure and the residue was distilled to give 1100 g (84% of theory) of neohexylmethyldichlorosilane.
