The synthesis of novel 3 - and 17-diphenylphosphino-androstane derivatives
via homogeneous catalytic P-C coupling is described. The products were char
acterized by H-1 and P-31 NMR measurements. According to the NMR investigat
ion of the PtCl2P2-type complexes, the steroidal phosphines are trans-coord
inated with respect to the Pt-centre exclusively.
