- A PROCESS FOR THE PREPARATION OF ORGANOSILICON COMPOUNDS CONTAINING -UNSATURATED CARBOXYLIC ACID RADICALS AND A COMPOSITION CONTAINING THE ORGANOSILICON COMPOUNDS

摘要

PURPOSE: A method for the preparation of organosilicon compounds containing alpha, beta-unsaturated carboxyl radical is provided, which has high selectivity of the organosilicon compounds. CONSTITUTION: A method for the preparation of organosilicon compounds(P) comprises; in the first process, obtaining organosilicon compounds(E) containing the radical represented by the following formula(3) by reacting organosilicon compound(H) containing the hydrogen atom which is combined the silicon directly, and olefin unsaturated compound(U) containing terminal double or triple bond represented by the following formula(2) in the presence of metal or compound of platinium group as catalyst; and the second process, removing the H-Z compound from organosilicon compound(E). wherein, A is biorganic radical, ohm is univalent organic radical containing terminal double or triple bond, R is H atom or methyl radical and Z is Cl, I, Br or 4-methyltoluenesulfonyl.
