A palladium(II) complex with a chelating (carboxy) phosphanoalkyl ligand
摘要:
rac-[SP-4-2]-{2-[(dimethylamino-kappaN)methyl]phenyl-kappaC(1)} {[2-(diphenylphosphanyl-kappaP)ferrocenyl](methoxycarbonyl)methyl-kappaC} palladium(II) (1) was synthesized by deprotonation of [SP-4-4]-chloro{2-[(dimethylamino-kappaN)methyl]phenyl-kappaC(1)} {rac-methyl 2-(diphenylphosphanyl)ferrocenylacetate-kappaP} palladium(II) with t-BuOK. Complex 1 was characterized by spectral methods and its reactivity studied. The structure of I was determined by X-ray crystallography and discussed in relation to other complexes with phosphanoalkyl ligands derived from phosphanoacetic esters. (C) 2004 Elsevier B.V.
