This work describes the dehydrogenative coupling of heteroarenes using a dimeric halo-bridged palladium(II) catalyst bearing an abnormal NHC ( aNHC) backbone. The catalyst can successfully activate the C-H bond of a wide range of heteroarenes, which include benzothiazole, benzoxazole, thiophene, furan, and N-methylbenzimidazole. Further, it exhibited good activity for heteroarenes bearing various functional groups such as CN, CHO, Me, OMe, OAc, and Cl. Additionally, we isolated the active catalyst by performing stoichiometric reaction and characterized it as the acetato-bridged dimer of ( aNHC)PdOAc by single-crystal X-ray study.

“…Moreover, from an environmental point of view, processes that use enzymes are greener, less hazardous and friendlier because they do not contaminate as in the case of using chemical catalysts [13,14]. In this context, the investigations regarding the kinetic resolution of R/S-ketoprofen with lipases are summarized chronologically within the Supplementary Information section in Table 1S (see refs.…”
