Abstract:
A novel and facile copper-catalyzed synthetic methodology was developed to access a large variety of 4-phosphoryl-substituted 1-naphthylamines by reacting various 1-naphthylamines with different diarylphosphine oxides in the presence of Cu(OAc)2 and Ag2CO3 in one pot under mild reaction conditions. This copper-catalyzed synthetic system was also suitable for being employed to synthesize 4-trifluoromethyl-substituted 1-naphthylamines by reacting various 1-naphthylamines with Togni's reagent in the presence of CuI and NaOAc in DMSO in one pot under mild reaction conditions.

Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.
