Deprotonated N,N′-disubstituted 1,8-diaminonaphthalenes (R2DAN2−; R = (CH3)2CH, C6H5, 3,5-Me2C6H3) were incorporated into Ta(V) complexes employing two methods. The direct proton transfer reaction of the parent amine, 1,8-(RNH)2C10H6, with TaMe3Cl2 led to elimination of methane and formation of TaCl3[1,8-(RN)2C10H6] (1, 2). Reaction of the dilithiated amido species, Li2R2DAN, with TaMe3Cl2 or [Ta(NEt2)2Cl3
