Optically active tertiary phosphine compound, transition metal complex comprising the same as ligand and process for preparing optically active organic silicon compound using said transition metal complex

A tertiary phosphine compound of the formula (1): STR1 in which R1 and R1' are hydrogen atoms or together form --CH=CH--CH=CH--; R2 and R3 together form a group of the formula (a): STR2 in which --.circle-solid. represent a bond to be bonded to the R3 group, and --? represents a bond to be bonded to the R2 group when R1 and R1 ' together form --CH=CH--CH=CH--, or when R1 is a hydrogen atom, R2 and R3 together form --CH=CH--CH=CH-- or R2 is a hydrogen atom and R3 is a substituted or unsubstituted alkyl group, or a substituted or unsubstituted phenyl group; A1 is a 3-trifluoromethylphenyl group or a 3,5-bis(trifluoromethyl)phenyl group when R1 is a hydrogen atom and R2 and R3 together form --CH=CH--CH=CH--, or a substituted or unsubstituted phenyl group when R1 is not a hydrogen atom or when R2 and R3 do not together form --CH=CH--CH=CH--.
