a Strategies to primary amines using NH3 and NH3·H2O as nitrogen source. b Challenges of N−H insertion of NH3·H2O. c TpBr3Ag-catalyzed two-phase system enables chemoselective carbene insertion into the N−H bonds of NH3·H2O. Tp, tris(pyrazolyl)borate; Ar, aryl; Tfs, 2-(trifluoromethyl)benzenesulfonyl.
