Nickel-catalyzed reductive methylation of alkyl halides and acid chlorides with methyl p-tosylate.

Zhuye Liang et al.

Organic letters, 16(21), 5620-5623 (2014-10-22)

Methylation of unactivated alkyl halides and acid chlorides under Ni-catalyzed reductive coupling conditions led to efficient formation of methylated alkanes and ketones using methyl p-methyl tosylate as the methylation reagent. Moderate to excellent coupling yields as well as excellent functional

Synthesis of gem-difluoroalkenes via nickel-catalyzed allylic defluorinative reductive cross-coupling of trifluoromethyl alkenes with epoxides.

Xiao-Yu Lu et al.

Organic & biomolecular chemistry, 18(19), 3674-3678 (2020-05-08)

A nickel-catalyzed defluorinative reductive cross-coupling of trifluoromethyl alkenes with epoxides has been developed. Various substituted trifluoromethyl alkenes and epoxides were found to be suitable reaction substrates. This reaction enabled C(sp3)-C(sp3) bond construction through allylic defluorinative cross-coupling of trifluoromethyl alkenes under

Nickel-catalyzed, sodium iodide-promoted reductive dimerization of alkyl halides, alkyl pseudohalides, and allylic acetates.

Michael R Prinsell et al.

Chemical communications (Cambridge, England), 46(31), 5743-5745 (2010-06-29)

The first general method for the reductive dimerization of alkyl halides, alkyl mesylates, alkyl trifluoroacetates, and allylic acetates is reported which proceeds with low catalyst loading (0.5 to 5 mol%), generally high yields (80% ave yield), and good functional-group tolerance.
