Abstract

The N, N-diphenylnitrenium ion (Ph2N+) was generated from the photolysis of a stable precursor, the 1-(N, N-diphenylamino)-2, 4, 6-trimethylpyridinium ion. The behavior of this nitrenium ion was studied by laser flash photolysis (LFP) and the analysis of its stable products. In accord with an earlier communication, Ph2N+ is found to have absorption maxima at 425 and 660 nm, to live for ca. 1.5 μs in CH3CN, and to react with Cl-at or near ...
