Nitrene-like Behaviour of Diazoazoles?
Farras, Jaume,Vilarrasa, Jaume
, p. 1127 - 1129 (1986)
Treatment of 4,5-dicyano-2-diazoimidazole, 2-diazoimidazole, amd 3-diazopyrazole with 1,1-dimethoxyethene affords azolo-as-triazines (1c), (3c), and (8c), respectively; the involvement as intermediates of either aziridines (d), arising from a 'nitrene-like reaction' of diazoazoles, or azoalkenes (b) should be questioned at present.

A green protocol for the synthesis of unsubstituted imidazoles has been demonstrated herein. The reaction is realized using commercially available lipase enzyme, porcine pancreas lipase (PPL) in water. The reaction conditions are selective and mild which helped to tolerate a wide variety of functional groups to give the desired products in good chemical yields. (Figure presented.).

Herein, we report a protocol for desulfonylation of aza-heteroaromatic rings via photoinduced electron transfer and hydrogen atom transfer. This general protocol has a wide substrate range and moderate to good yields. The utility of the method was demonstrated by the chemoselective desulfonylation of a molecule containing both an aliphatic and an aromatic sulfonamide. (Figure presented.).
