Abstract
Use of a nickel catalyst in combination with a photoredox catalyst and light leads to much more active alkylation catalysts for the synthesis of tertiary nitroalkanes via alkylation of secondary nitroalkanes using aliphatic iodides. The conditions are scalable as well as air and moisture tolerant. Importantly, reduction of the tertiary nitroalkane products allows rapid access to α-tertiary amines.
