Several rhodium(I) complexes containing chiral phosphine, (+) DIOP, (+> BINAP, (S,S) CHIRAPHOS, and (S)(R) BPPFA, have been found to be effective as catalyst for the asymmetric hydrobomtion of pm&h-al alkenes with catecholborane (1,3,2benzodioxaborole) to give optically active 2-alkyl-1,3,2-benzodio
