RHODIUM(III) AND RUTHENIUM(II) COMPLEXES WITH THE CHIRAL PHOSPHINE-ALCOHOL Ph2PCH2CHMeCH2OH: SYNTHESIS AND CHARACTERISATION
Reaction of the dinuclear complex [{(eta5-C5Me5)RhCl} 2(µ-Cl)2] with the chiral phosphine (R)-Ph2PCH2CHMeCH2 OH leads to the complex [{(eta5-C5Me5)RhCl 2(eta¹-Ph2PCH2 CHMeCH2OH-P)](1). This reaction, in the presence of AgBF4, yields the cationic compound [{(eta5-C5Me5)RhCl(eta²- Ph2PCH2CHMeCH2OH-P,O...
