Oxidative Addition Reactions of Selenocyanogen with Tetrakis-(triphenylphosphine)palladium(O) and -platinum(O)

摘要

The oxidative addition reactions of selenocyanogen with M(P(C6H5)3)4 (M #x2ED; Pd, Pt) in ethyl ether: pentane:ethanol (5:5:2 by volume) at #x2212;78#xB0;C under nitrogen lead to the formation of the complexes trans-M(P(C6H5)3)2(SeCN)2. Although the selenocyanates are Se-bound in both complexes in the solid state, dissolution of the Pt(II) complex in methylene chloride or DMF leads to partial isomerization to the N-bonded form.
