In site preparation of Pd(II)–MoS2 complex: A new high-efficiency catalyst for alkenylation of heteroaromatics by direct CH bond activation

• A Pd catalyst was designed by affording Pd2+ salt on the surface of single-layered MoS2.
• This metal salt and molybdenum disulfide complex offered several advantages, including easy preparation and low cost.
• Direct CH activation of indoles, furans and thiophenes was carried out to combine with terminal olefins with 0.2% amount of the catalyst.
• This easy-prepared catalyst also performed high efficiency in several other kinds of CC coupling reactions.

Pd(II)–MoS2 catalyst was designed by affording Pd2+ salt on the surface of single-layered molybdenum disulfide nanosheets.. Based on the dispersible template, this metal salt and molybdenum disulfide complex offered several advantages, including easy preparation, low cost, and capability to prepare excellent dispersible metal ion cluster nanostructures. The application of this complex in alkenylation of heteroaromatics was reported. Direct CH activation of indoles, furans and thiophenes was carried out to combine with several kinds of terminal olefins. This catalyst also performed high efficiency in several other kinds of coupling reactions. Thus, a universal suitable catalyst for CH activation and CC bond formation was invented by a convenient in situ preparation.
