Dhungana, Roshan K. published the artcileNi-catalyzed regioselective 1,2-dialkylation of alkenes enabled by the formation of two C(sp3)-C(sp3) bonds, Formula: C12H16BBrO2, the publication is Journal of the American Chemical Society (2020), 142(50), 20930-20936, database is CAplus and MEDLINE.
The authors disclosed a Ni-catalyzed vicinal difunctionalization of alkenes with benzyl halides and alkylzinc reagents, which produces products with two new alkyl-alkyl bonds. This alkene dialkylation is effective in combining secondary benzyl halides and secondary alkylzinc reagents with internal alkenes, which furnishes products with three contiguous all-carbon secondary stereocenters. The products can be readily elaborated to access complex tetraene, benzosuberene, and bicyclodecene cores. The reaction also features as the most efficient alkene difunctionalization process to date with catalyst loadings down to 500 ppm and the catalytic turnover number (TON) and turnover frequency (TOF) registering up to 2 x 103 and 165 h-1 at rt, resp.
