Palladium carbene complexes as persistent radicals.

ABSTRACT: A series of palladium(ii) radical carbene complexes, [PC˙(sp²)P]PdI, [PC˙(sp²)P]PdBr, and [PC˙(sp²)P]PdCl (PC(sp³)H₂P = bis[2-(di-iso-propylphosphino)-phenyl]methane), is described. Compound [PC˙(sp²)P]PdI dimerizes to {[PC(sp²)P]PdI}₂ in the solid state, akin to the formation of Gomberg's dimer. While the bromo and the iodo derivatives could be obtained from the oxidation of [PC(sp²)P]Pd(PMe₃) by the respective dihalogens, a halogen transfer reaction from CH₂Cl₂ was used for the formation of [PC˙(sp²)P]PdCl. The halogen transfer from CH₂X₂ (X = Cl, Br, I) could be used to obtain all three radical carbene palladium complexes an
