Abstract

Cobalt (III) complexes,[CoCl2 (L1) 2](PF6)(1, L1= N-methyl-N-(2-pyrimidinyl) imidazolylidene),[CoCl (L2) 2](PF6) 2 (2, L2= N-picolyl-(2-pyrimidinyl) imidazolylidene),[Co (L3) 2](PF6) 3 (3, L3= bis (N-2-pyrimidylimidazolylidenyl) methane) and [CoCl2 (L3)](PF6)(4) have been prepared from the corresponding pyrimidine functionalized imidazolium salts [HL1](PF6),[HL2](PF6), and [H2L3](PF6) 2via in situ generated silver carbene complexes ...
