Abstract
Dichlorobis(tricyclohexylphosphine)palladium(II), 1, is prepared in qu antitative yield by the reaction of Na-2[PdCl4] with Cy(3)P in aqueous ethanol. Complex 1 possesses trans geometry in solution (NMR) and in the solid state (X-ray diffraction). The reaction between 1 and concen trated alkali in the presence of tricyclohexylphosphine and catalytic amounts of 18-crown-6 results in bis(tricyclohexylphosphine)palladium( 0) in 85-90% yield. Crystallographic data for 1: space group P1, a = 1 0.161(4) Angstrom, b = 10.604(4) Angstrom, c = 9.902(4) Angstrom, V = 916.0(6) Angstrom(3), Z = 1, R = 0.027, R(w) = 0.030.
