58% | With [Pd(allyl)(BrettPhos)]OTf; sodium t-butanolate; In toluene; at 90℃;Schlenk technique; Inert atmosphere; | General procedure: The N-aryl aminocyclopropanes were synthesized according to the literature.[5] An oven-dried Schlenk tube equipped with a stirring bar was charged with [Pd(allyl)(brettphos)]OTf (0.025 mmol, 0.5 mol %), and NaOt-Bu (7.5 mmol). The tube was evacuated and backfilled with nitrogen for three times. The amine (7.5mmol), aryl bromine (5.0 mmol), and anhydrous toluene (40 mL) were added sequentially via syringe. The tube was placed in a preheated oil bath and the contents were stirred for the indicated time. The tube was then removed from the oil bath and allowed to cool to room temperature. The reaction mixture was diluted with 10 mL of dichloromethane and filtered through a pad of Celite. The solution was concentrated in vacuo, and the residue was purified on silica gel using n-hexane/ethyl acetate as eluent. |
