Cobalt-Catalyzed C-H Activation
Catalytic C-H activation has emerged as a powerful tool for sustainable syntheses. In the recent years, notable success was achieved with the development of cobalt catalyzed C-H functionalizations with either in situ generated or single-component cobalt-complexes under mild reaction conditions. Herein, recent progress in the field of organometallic cobalt-catalyzed C-H activation is reviewed until November 2015
Ruthenium(II)-Catalyzed C−C Arylations and Alkylations: Decarbamoylative C−C Functionalizations
Ruthenium(II)biscarboxylate catalysis enabled selective C-C functionalizations by means of decarbamoylative C-C arylations. The versatility of the ruthenium(II) catalysis was reflected by widely applicable C-C arylations and C-C alkylations of aryl amides, as well as acids with modifiable pyrazoles, through facile organometallic C-C activation
CH Alkenylations with Alkenyl Acetates, Phosphates, Carbonates, and Carbamates by Cobalt Catalysis at 23 degrees C
Inexpensive cobalt catalysts with N-heterocyclic carbene ligands enable direct arene alkenylations with easily accessible alkenyl acetates through regioselective CH/CO functionalizations in a stereoconvergent fashion. The versatile cobalt catalyst was broadly applicable and thus also allowed for the efficient conversion of alkenyl phosphates, carbonates, and carbamates at ambient temperature.European Research Council under the European Community [307535
Selective Synthesis of Indoles by Cobalt(III)-Catalyzed CH/NO Functionalization with Nitrones
The redox-neutral annulation of alkynes by differently decorated nitrones set the stage for a step economical access to indoles with ample substrate scope. The redox-neutral C-H/N-O functionalization process proceeded through kinetically relevant C-H activation by carboxylate assistance, and displayed an excellent site- and regio-selectivity with unsymmetrical nitrones and alkynes
