ABSTRACT:
A method for making a silylalkoxymethyl halide at good yield represented by the formula:in-line-formulae description="In-line Formulae" end="lead"?R1R2R3Si—R4—O—CH2Xin-line-formulae description="In-line Formulae" end="tail"?wherein R1, R2, and R3are an alkyl, cycloalkyl, aryl group, or a halogen atom, R4is a divalent hydrocarbyl group having 1 to 10 carbon atoms, and X is a halogen atom, by reacting:(a) a silyl alcohol compound with the formula R1R2R3Si—R4—OH wherein R1, R2, R3and R4are defined as above, with(b) formaldehyde or a polymer thereof, and(c) a halosilane.
