Abstract

The development of photochemical methods for generating nitrenium ions 1,2 led to renewed interest in these short-lived species. The early 1990s saw the first laser flash photolysis (LFP) studies applied to these reactive intermediates. The initial experiments used photoisomerization of anthranilium ions to generate nitrenium ions (1). 3 This route is inherently limited to producing N-alkyl-N-arylnitrenium ions having a carbonyl group on the aromatic ring (2).
