METHOD FOR PRODUCING DISILYL ACETAL AND ALDEHYDE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing disilyl acetals and aldehydes useful as an intermediate for an organic synthesis. SOLUTION: This method for producing the disilyl acetals expressed by the general formula RCH(OSiR<1> R<2> R<3> )2 or RCH(OSiR<1> R<2> R<3> )(OSiR<4> R<5> R<6> ) is provided by performing a reaction of a carboxylic acid expressed by the general formula: RCOOH or a carboxylic acid silyl ester expressed by the general formula: RCOOSiR<4> R<5> R<6> with a hydrosilane expressed by the general formula: HSiR<1> R<2> R<3> in the presence of a ruthenium catalyst. The method for producing the aldehydes expressed by the general formula: RCHO is characterized by performing a reaction of the disilyl acetals in the presence of a transition metal catalyst.
