A process for the continuous preparation of 3-halopropylorganosilanes of the general structurewhere:R is CH3, C2H5, C3H7, OCH3, OC2H5 or OC3H7,X is F, Cl, Br or I,Y is F, Cl, Br or I, anda and b are each one of the numbers 0, 1, 2 or 3 and the sum a+b is 1, 2 or 3, comprising reacting, as starting materials, an allyl halide with a silane carrying at least one H atom,wherein the starting materials are present in stoichiometric amounts or one of the starting materials is present in substoichiometric amounts,wherein the reaction carried out is a partial reaction of from 10% to 80%, on a molar basis, of the starting materials, based on either material, when both are present in stoichiometric amounts, or based on the substoichiometric material.
