Organoboranes react with nitrogen-13 labeled ammonia to produce alkylamines in moderate yield. When 13N labeled ammonia was bubbled into a tetrahydrofuran solution containing 0.5M tridecylborane, 1-[13N]aminodecane was formed in 25-30 min from the end of bombardment (EOB) in 40-60% overall yield. 1-
