This work illustrates a reductive cross-electrophile coupling protocol for trifluoromethylation of alkyl iodides under Cu-catalyzed/Ni-promoted reaction conditions. The use of diboron esters as the terminal reductant allows the effective generation of the alkyl-CF3 products with excellent functional group tolerance and broad substrate scope. A mechanism involving a reaction of alkyl-Cu with Togni's reagent was proposed.

Three novel catalysts based upon cyclic β-aminophosphonate derivatives 13 were designed to catalyze the asymmetric Michael addition reactions of ketones to β-nitrostyrenes. Among the catalysts that have been prepared in this study, cyclic β-aminophosphonic acid monoethylester 3 showed the highest catalytic ability, giving the corresponding Michael adduct in good yields, high enantioselectivities (up to 92%ee), and high diastereoselectivities (syn:anti up to 95:5).
