Reaction of methyl arylzincs with acetone O-(mesitylenesulfonyl)oxime in THF in the presence of CuCN at room temperature is efficient in selective electrophilic amination of aryl carbanions. This procedure allows for the preparation of arylamines in moderate to good yields and provides an efficient and atom economic alternative to existing amination methods for diarylzincs.

Group selectivity in the allylation of mixed (n-butyl)(phenyl)zinc reagent can be controlled by changing reaction parameters. CuCN-catalyzed allylation in tetrahydrofuran (THF)-hexamethylphosphoric triamide is n-butyl selective and also γ-selective in the presence of MgCl 2 , whereas CuI-catalyzed allylation in THF in the presence of n-Bu 3 P takes place with a n-butyl transfer:phenyl transfer ratio of 23:77 and an α:γ transfer ratio of phenyl of 76:24. NiCl 2 (Ph 3 P) 2 -catalyzed allylation in the presence of LiCl is phenyl selective with an α:γ ratio of 65:35. The reaction of methyl-or n-butyl(aryl)zinc reagents with an allylic electrophile in THF at room temperature in the presence of NiCl 2 (Ph 3 P) 2 catalyst and LiCl as an additive provides an atom-economic alternative to aryl-allyl coupling using diarylzincs.The ratio of GC yields of 6a and 7a. e The ratio of GC yields of 6b and 7b. f Stoichiometric cuprate reagent derived from n-BuPhZn and CuI (or CuCN) was prepared in situ. g X = Cl, Br and SCN. h X = Cl, OAc, OTf and acac. /journal/aoc d The ratio of GC yields of (6a + 7a) and (6b + 7b). e The ratio of GC yields of 6a and 7a. f The ratio of GC yields of 6b and 7b.The ratio of GC yields of (6a + 7a) and (6b + 7b). e The ratio of GC yields of 6a and 7a. f The ratio of GC yields of 6b and 7b.Reactivity of mixed organozinc and mixed organocopper reagents: 11
