Reaction of the 5-hydroacenaphthylene anion with benzyl halides proceeds at carbon atom 1 as well as at carbon atom 2a, in the latter case creating a quaternary centre. The hardness-softness of the electrophiles was shown to play only a minor role in determining the regioselectivity of the reaction

This calculation introduces a promising way to catalyze gas-phase S N 2 reactions at a unimolecular level by using an excess electron (EE) as an ''electron solvent''. The EE participation leads to very favorable energetics for the reaction, by neutralizing the created positive charge as the reaction
Time-resolved (TR) ESR was employed to investigate the reaction of diphenylphosphinoyl reactive free radicals with N-phenyltert-butylnitrone (PBN), which were produced by laser flash photolysis (YAG laser, 355 nm) of diphenyl-2,4,6-trimethylbenzoyl phosphine oxide (DPO). The TR ESR and continuous wa
