Phosphorus double functionalisation by template condensations; formation of P–C and P–O bonds from metallocycles. Synthesis and crystal structure of cis-[PdCl2{Ph2PCHC(Ph)OP(Ph)(o-C6H4CH2NMe2H}]Cl

Abstract

The air-stable bis-chelate complexes cis-[[graphic omitted])Ph}₂](1) and [(L)[graphic omitted])Ph}][(3), (LH)= dimethylbenzylamine; (5), (LH)= 8-methylquinoline] react smoothly with 1 equiv. of PhPCl₂ to afford coupling products [(2), and (4) and (6), respectively], involving the O atom of the enolate ligand and the Pd-bound C atom of the cyclometallated ligand.
