An expedient catalytic approach for α-olefination of nitriles using secondary alcs. with the liberation of mol. hydrogen and water as the only byproducts is reported. This reaction is catalyzed by a molecularly defined manganese(I) pincer complex and operates in the absence of any hydrogen acceptors. A broad range of substrates including cyclic, acy-clic, and benzylic alcs. as well as various nitrile derivatives such as arylmethyl and hetroarylmethyl nitriles are employed in the reaction to provide diverse range of α-vinyl nitriles in good to excellent yields. Mechanistic studies showed that the reaction proceeds via dehydrogenative pathway and the activation of α(C-H) bond of the alc. is the rate determining step. Kinetic experiments clearly indicate the first order rate kinetics for alcs. as well as nitriles.Bromopentacarbonylmanganese(I)(cas: 14516-54-2COA of Formula: C5BrMnO5) was used in this study.
Bromopentacarbonylmanganese(I)(cas: 14516-54-2) has many other uses. It is used in the formation of (eta6-arene)tricarbonylmanganese(I) by reacting with arene (arene= hexamethyl benzene, 1,2,4,5-tetramethyl benzene, mesitylene, p-xylene and toluene) in the presence silver salt.COA of Formula: C5BrMnO5
