Highly diastereoselective dihydride formation by activation of methanol with IrCl((S)-binap)(PPh3).
Reaction of [IrCl((S)-binap)(PPh3)] ((S)-3) with methanol gave one of the diastereomers of the cis,mer-dihydride, cis,mer-OC-6-44-A-[IrCl(H2)((S)-binap)(PPh3)] ((S)-4a) stereoselectively, the structure of which was determined crystallographically, whereas the reaction of (S)-3 with H2 produced a 1:1 mixture of the diastereomers of the cis,mer-dihydride, (S)-4a and cis,mer-OC-6-44-C-[IrCl(H2)((S)-binap)(PPh3)] ((S)-4b).
