Palladium complexes of thio/seleno‐ether containing N‐heterocyclic carbenes: efficient and reusable

Eur. J. Inorg. Chem. 2020, 532-540

Three Pd(II) catalysts, two bearing (S,CNHC) half-pincer and one bearing (Se,CNHC,S) type pincer, have been synthesized and applied in the regioselective C-H bond arylation of imidazole. All the complexes were found to be efficient under mild conditions. The (Se,CNHC,S) pincer ligated Pd(II) complex, which is the first example of this type, was found to be utmost effective amongst them.
