SYNTHESIS AND COORDINATION PROPERTIES OF CHIRAL BIDENTATE P,O-DONOR LIGANDS
Reaction of the chiral compound (S)-(+)-BrCH2CHMeCH2OH with Ph2PK in the presence of lithium diisopropylamide (LDA) and BH3/THF yields the monophosphine (S)-Ph2P(BH3)CH2CHMeCH 2OH(1). The reaction of 1 with ClOSO2Me/Et3N or NaH/MeI gives rise to the formation of the general compound (S)-Ph2P(BH3)CH2...
