PREPARATION OF ORGANOXYSILYL OR SILOXY-CONTAINING ETHYLNORBORNENE COMPOUND

摘要

PROBLEM TO BE SOLVED: To provide an efficient preparation method with improved reactivity and addition selectivity to a vinyl group/ring internal double bond, when an organoxysilyl or organoxysiloxy-containing ethylnorbornene compound is prepared by generating hydrosilylation reaction of 5-vinyl-2-norbornene with a hydrogen organoxysilane compound or a hydrogen organoxysiloxy compound by using a platinum catalyst.;SOLUTION: This method for preparation of an organoxysilyl or siloxy-containing ethylnorbornene compound represented by general formula (2) (R¹ is a 1-10C unsubstituted or substituted monovalent hydrocarbon group or a siloxy group; R² is a 1-10C unsubstituted or substituted monovalent hydrocarbon group or a silyl group; R¹ and R² may be the same or different respectively; and n is an integer of 0-2.) comprises hydrosilylating 5-vinyl-2-norbornene with a hydrogen organoxysilane or siloxy compound represented by general formula (1): HSiR¹_n(OR²)_3-n (1) (R¹, R² and n are the same.), by using a platinum compound-containing catalyst in the presence of an ammonium salt. According to this invention, the objective organoxysilyl group or siloxy-containing ethylnorbornene compound can be effectively prepared at high reactivity and selectivity by reacting 5-vinyl-2-norbornene with a hydrogen organoxysilane or siloxy compound in the presence of the ammonium salt.;COPYRIGHT: (C)2013,JPO&INPIT
