Palladium-catalyzed Suzuki--Miyaura coupling of N-benzenesulfonyl-3,4-dibromopyrrole with a variety of arylboronic acids gave the corresponding 3,4-diarylpyrroles in high yields. The 3,4-differentially arylated pyrroles could also be prepared by step

Highly functionalized benzenes were precisely synthesized via multi-step processes consisting of ruthenium-catalyzed [2+2+2] cycloaddition of diiododiynes with an ethynylboronate or terminal alkynes, and subsequent chemo- and regio-selective palladiu

Cobalt/N-heterocyclic carbene system or cobalt/diamine combination effectively catalyzes sequential cyclization/cross-coupling reactions of 6-halo-1-hexene derivatives with trialkylsilylmethyl, 1-alkynyl, and aryl Grignard reagents. The sequential cy

The copper complexes with bis(oxazoline) or azabis(oxazoline) ligands, once supported on laponite clay by electrostatic interactions, are able to catalyze the insertion of carbenoids in benzylic C-H bonds. In contrast with rhodium catalysts, they are
