Ruthenium-catalyzed para-selective oxidative cross-coupling of arenes and cycloalkanes
A novel, direct para-selective oxidative cross-coupling of benzene derivatives with cycloalkanes catalyzed by ruthenium was developed. A wide range of arenes bearing electron-withdrawing substituents was functionalized directly with simple cycloalkanes with high para-selectivity; arenes with electron-donating groups were mainly para-functionalized. Benzoic acid can be used directly.

Pincer thioamide and pincer thioimide palladium complexes catalyze highly efficient negishi coupling of primary and secondary alkyl zinc reagents at room temperature
Pincer thioamide PdII complex 2 was prepared, and its reaction with cyclohexylzinc chloride yielded novel pincer thioimide PdII complex 3 besides Pd0 species. The structures of complexes 2 and 3 were confirmed by X-ray ana
