The nucleophilicsubstitutionreactions of (Y)-indan-2-yl (Z)-arenesulfonates with (X)-anilines in methanol at 55.0 °C are reported. Sign reversals in all three second-order cross-interaction constants, ρxy, ρyz and ρxz, are observed at non-interaction points z=–0.11 (ρxy= 0), x=–0.02 (ρyz= 0) and Y= 0.43 (ρxz= 0) respectively, which have been ascribed to an unusually large third-order cross-interaction

found to be effective for the direct deaminative coupling of two primaryamines to form secondary amines. The catalyst 1/L1 was highly chemoselective for promoting the coupling of two different primaryamines to afford unsymmetric secondary amines. The analogous coupling of aniline with primaryamines formed aryl-substituted secondary amines. The treatment of aniline-d7 with 4-methoxybenzylamine led to
