alkyl derivatives affords acyl complexes Pd(COR)Cl(L2) and related iminoacyl derivatives have also been obtained by the analogous reaction with tert-butyl-isocyanide. New alkyl and acyl species containing bis(pyrazolyl)borate ligands have been prepared by halide metathesis in the Pd(R/COR)Cl(PMe3)2 complexes. During the course of these reactions one equivalent of PMe3 is liberated. The complex Bp∗Pd(CH2SiMe3)(PMe3)
