The 3a/Pd(OAc) 2 catalyst system promotes, for the first time, efficient coupling of vinyl bromides with a variety of amines to produce imines and enamines at room temperature. ( 3a) ( 5) was also employed successfully in C−N coupling reactions while the crotyl analogue was less efficacious.The air-stable palladium complex (η 3-cinnamyl)PdCl An important strength of our protocol is the use of lower palladium loadings than those reported earlier, without compromising yields. Heterocyclic bromides and chlorides underwent clean couplings with amines in excellent yields. BOC-protected amines also participated efficiently. Moreover, an aryl chloro group can be preserved in the presence of a bromo substituent under our reaction conditions. Aryl halides possessing other functional groups including cyano, amino, trifluoromethyl, and phenol, coupled with equal ease, producing highly functionalized amines in good to excellent yields. By employing Pd(OAc) 2, Cs 2CO 3, or NaOH, and the new ligand ( t-Bu) 2PN P(i-BuNCH 2CH 2) 3N ( 3a), an electronically diverse array of aryl bromides and chlorides possessing base-sensitive substituents (nitro, ester, and keto) provide coupling products with bulky aryl amines in good to excellent yields.
