Chlorohydridobis tricyclohexylphosphine palladium

The corresponding palladium complexes are also known.3 Since the original preparative method is rather complicated, a simpler one4 for the preparation of chlorohydridobis(tricyclohexylphosphine)palladium is described in this synthesis. ... 

Chlorohydridobis(tricyclohexylphosphine)palladium is a white solid. It is thermally stable at ambient temperatures. It is not very sensitive to air in the solid state, but it is advisable to store it in an inert atmosphere. It is soluble in benzene and tetrahydrofuran. The infrared spectrum shows a sharp v(Pd—H) band at 2002 cm -1 (Nujol mull). The high-field H nmr spectrum in benzene solution shows a triplet at t24.4 (TMS) with 7PH 4.1 Hz. The splitting is caused by the coupling of the hydride proton with two equivalent 31P nuclei. This is consistent with a trans square-planar configuration.
