Abstract

Abstract: High pressure mass spectrometry was used to measure the kinetics for electron transfer between 54 pairs of tetraalkylhydrazines containing acyclic and five-to seven- membered cyclic and bicyclic rings. Rate constants for electron transfer vary between 18 and 0.03 X lo-" cm3 molecule-'s-'at 550 K. Variable-temperature measurements were made on five pairs over a 77-120 range. The (Me, N),+,(EtMeN), pair gave E,= 2.7 kcal/mol. The ...
