Abstract

Intermolecular equilibrium isotope effects (EIEs) were measured (26.5° C) and calculated for (silox) 2 (tBu3SiND) TiRD (1-ND-RD)+ RHH⇄(silox) 2 (tBu3SiNH) TiRH (1-RH)+ RDD: RHH/RDD= CH4/CD4, 2.00 (6), calcd 1.88; C2H6/C2D6, 2.22 (8), 1.93; cC3H6/cC3D6, 1.71 (4), 1.48; C2H4/C2D4, 1.41 (11), 1.34; C6H6/C6D6, 1.22 (7), 1.26; C7H8/C7D8 (50.0° C), 1.59 (6), 1.55.
