Terminal pentafluorobenzimidoylpalladium(II) complexes. X-ray structure of trans-[Pd{C(C6F5)NMe}Cl(CNMe)2] (original) (raw)

1985, Journal of Organometallic Chemistry

The preparations of the complexes truns-[Pd{C(C,F,)=N(Ri)}C1(CNR2)2] and [Pd{C(C,F,)=N(Ri)}(CNR2),]X (R' = Me, p-Tol; R2 = Me, p-Tol, Bu'; X = ClO, or BPh,) from [Pd,{ ~-C(C6F5)N(Ri)}2C12(CNR2)2] are described. The splitting of the imidoyl bridges is accompanied 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 truns-[Pd{C(C,F,)=N(Me)}Cl(CNMe),]. Attempted preparations of [Pd{C-(C,F,)=N(R')}Cl(PPh,),] from [Pd,{ ~-C(C6F5)=N(R)}2C12(PPh,)2] led to elimination of CNR and formation of truns-[Pd(C,F,)Cl(PPh,),]; this is the first example of isonitrile elimination in palladium chemistry. * Further crystallographic details (structure factors, H atom coordinates, temperature factors) can be ordered from the Fachinformationszentrum Energie Physik Mathematik, D-7514 Eggenstein-Leopoldshafen 2, F.R.G.
