dc.description.abstractReaction of the chiral compound (S)-(+)-BrCH2CHMeCH2OH with Ph2PK in the presence of lithium diisopropylamide (LDA) and BH3/THF yields the monophosphine (S)-Ph2P(BH3)CH2CHMeCH2OH(1). The reaction of 1 with ClOSO2Me/Et2N or NaH/Mel gives rise to the formation of the general compound (S)-Ph2P(BH3)CH2CHMeCH2OR [R = SO2Me (2), Me (5)], which by treatrent with pyrrolidine affords (S)-Ph2PCH2CHMeCH2OR [R = SOMe (4), Me (6)). The monophophines 4, 6 and (S)-PPh2CH2CHMeCH2OH react with [{Cp*IrCl(mu-Cl)(2)] to give the neutral compounds [Cp*IrCl2(PPh2CH2CHMeCH2OR-P)], where only the compound with R - H (7) was fully characterized. Complex 7 reacts with AgBF4 yielding the cationic complex [Cp*IrCl(PPh2CH2CHMeCH2OH-PO)]BF4 (8) in which the ligand acts in its bidentate form. Similar synthetic results were obtained using [jCp*IrI(mu-I)(2)] as starting complex.
