Abstract
Increasing electron demand in the reactions of G-NMBH anions with substituted phenyldimethylsulfonium ions decreases the α-effect for the methyl transfers toward 1.0 (zero effect). An extrapolation shows the possibility of an inverse effect (< 1.0). The reactivity of G-NMBH anions correlates with SET parameters and with the known propensity of phenyldimethylsulfonium ions to accept a single electron into a σ* CS orbital concomitant ...
