The preparations of the complexes trans1)>Cl(CNR²)2> and 1)>(CNR²)2>X (R¹= Me, p-Tol; R²= Me, p-Tol, Bu^t; X= ClO4 or BPh4) from 1)>2Cl2(CNR²)2> are described.The splitting of the imidoyl bridges is accompained by an isomerization of the imidoyl group from the syn to the anti conformation as shown by a single crystal X-ray diffraction study of trans-Cl(CNMe)2>.Attempted preparations of 1)>Cl(PPh3)2> from 1)>2Cl2(PPh3)2> led to elimination of CNR and formation of trans-; this is the first example of isonitrile elimination in palladium chemistry.
