PURPOSE: To obtain the title substance useful as a raw material for medicine, synthetic high polymer, etc., by reacting a halogenated organosilicon compound with a vinyloxy compound in the presence of a catalyst of the group VIII metal and fluoride ion. n CONSTITUTION: A compound expressed by formula I (R 1 is alkyl, alkenyl, aryl, alkynyl, etc.; R 2 to R 4 are halogen, alkyl, aryl, alkenyl, alkynyl, etc.) is reacted with a compound expressed by formula II (R 5 to R 7 are alkoxycarbonyl, alkoxy, CN, acyl, H, alkyl, etc.; R is acyl, sulfonyl, etc.) in the presence of a catalyst of the group VIII metal [e.g., tetrakis(triphenylphosphine)palladium] and fluoride ion (e.g. tetrabutylammonium fluoride), preferably in an aprotic polar solvent such as DMF at ambient temperature to 80°C to provide the compound expressed by formula III. n COPYRIGHT: (C)1990,JPO&Japio |
