Reactions of carbodi-imides with palladium(II) compounds

New dihalogenobis(carbodi-imide)palladium(II) compounds are formed in the reactions between di-t-butyl- and methyl-t-butylcarbodi-imides and (PhCN)PdX (X = Cl and Br) in dichloromethane solution. In methanol solution, 1,2-addition of solvent to di-o-tolyl-, dicyclohexyl- and methyl-t-butylcarbodi-imides is promoted by Pd, and dihalogenobis(isourea) complexes are obtained. Structures of the compounds are discussed on the basis of i.r. and H n.m.r. observations
