Abstract
In the presence of a catalyst and a cycloalkane compound represented by formula (3): wherein R3, R4, R5, R6, R7, R8, R9, and R10 are the same or different and each is a halogen atom, an alkyl group, or a fluoroalkyl group; an alkene compound represented by formula (2): wherein X1, X2, R1, and R2 are as defined above; is reacted with a hydrogen-containing gas to hydrogenate the alkene compound represented by formula (2), whereby an alkane compound represented by R1CHX1CHX2R2, wherein X1 and X2 are the same or different and each is a halogen atom, and R1 and R2 are the same or different and each is an alkyl group or a fluoroalkyl group; can be synthesized in such a manner that (S),(R)-isomer, (R),(R)-isomer, and (S),(S)-isomer are co-produced.
