<p><P>PROBLEM TO BE SOLVED: To provide an efficient production method capable of improving regioselectivity, while maintaining reactivity, when producing a bis(organoxysilyl) alkane compound by generating an addition reaction by using a diene compound, a hydrogen organoxysilane compound and a catalyst. <P>SOLUTION: In this method, when hydrosilylating by using a platinum-containing catalyst, a diene compound represented by following formula (1) CH<SB POS="POST">2</SB>=C(R<SP POS="POST">1</SP>)-(CH<SB POS="POST">2</SB>)<SB POS="POST">m</SB>-C(R<SP POS="POST">1</SP>)=CH<SB POS="POST">2</SB>(1) (R<SP POS="POST">1</SP>is a hydrogen atom or a monovalent hydrocarbon group, and m is an integer of 0-14), and a hydrogen organoxysilane compound represented by following formula (2) HSiR<SP POS="POST">2</SP><SB POS="POST">n</SB>(OR<SP POS="POST">3</SP>)<SB POS="POST">3-n</SB>(2) (R<SP POS="POST">2</SP>and R<SP POS="POST">3</SP>are each monovalent hydrocarbon group, and n is an integer of 0-2), a≥0.1 mass% aliphatic nitrile compound is allowed to exist with respect to the diene compound, to thereby produce bis(organoxysilyl) alkane compound represented by following formula (3) (R<SP POS="POST">3</SP>O)<SB POS="POST">3-n</SB>R<SP POS="POST">2</SP><SB POS="POST">n</SB>Si-CH<SB POS="POST">2</SB>-CH(R<SP POS="POST">1</SP>)-(CH<SB POS="POST">2</SB>)<SB POS="POST">m</SB>-CH(R<SP POS="POST">1</SP>)-CH<SB POS="POST">2</SB>-SiR<SP POS="POST">2</SP><SB POS="POST">n</SB>(OR<SP POS="POST">3</SP>)<SB POS="POST">3-n</SB>(3) (R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>, R<SP POS="POST">3</SP>, m and n are the same as described above). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
