Synthesis of tetra- and pentacoordinate palladium complexes of functionalized N-heterocyclic carbenes and a comparative study of their catalytic activities†
Abstract
Palladium complexes, [Pd(1-butyl-3-((7-methyl-1,8-naphthyridin-2-yl)methyl)imidazolylidene)2](PF6)2 (1), [Pd(3-methyl-1-(pyrimidin-2-yl)imidazolylidene)2(CH3CN)](PF6)2 (4), [Pd(3-benzyl-1-(pyrimidin-2-yl)imidazolylidene)2(CH3CN)](PF6)2 (5), [Pd(3-ethyl-1-(pyrimidin-2-yl)imidazolylidene)2Cl](PF6) (6), and [Pd(3-benzyl-1-(pyrimidin-2-yl)imidazolylidene)Cl2] (7), have been prepared viatransmetallation of corresponding in situ generated silver-
