The NAD(+) subunit 1-methyl-3-carbamoyl pyridinium cation (or 1-methyl nicotinamide cation, MNA(+)) forms an ion pair with BH3CN- which shows a new absorption (lambda (max) = 453 nm) which is assigned to an outer-sphere charge transfer (OSCT) transition from BH3CN- to MNA(+). At r.t. this ion pair is not stable and undergoes a hydride transfer from BH3CN- to MNA(+) with the formation of MNAH. At -77 degreesC this ion pair is persistent but the hydride transfer occurs as a photoreaction which is induced by OSCT excitation. (C) 2000 Elsevier Science S.A. All rights reserved.
