Abstract

Abstract: Treatment of 3-(4-chlorophenoxy)-1, 2-propanediol with MsCl and subsequently with NaPPh, gave the diphosphine 2, which could be converted to the silylated phosphines 3 and 4 and attached to silica gel. It was determined experimentally that these ligands are distributed randomly on the silica surface. The synthesis of (P2) RhNBD+ BF4-(14) and (P2) RhC3HS (16)(P2= 4) is described. Both 14 and 16 are precursors of monohydride ...
