Transannulation of 1-sulfonyl-1,2,3-triazoles with heterocumulenes

Readily available 1-mesyl-1,2,3-triazoles are efficiently converted into a variety of imidazolones and thiazoles by Rh(II)-catalyzed denitrogenative reactions with isocyanates and isothiocyanates, respectively. The proposed triazole-diazoimine equilibrium results in the formation of highly reactive azavinyl metal-carbenes, which react with heterocumulenes causing an apparent swap of 1,2,3-triazole core for another heterocycle.

N-H insertion reactions of primary ureas: The synthesis of highly substituted imidazolones and imidazoles from diazocarbonyls

Primary ureas have been used as substrates in rhodium-catalyzed N-H insertion reactions with an array of diazocarbonyls. The insertion reaction is efficient and gives excellent selectivity and yields. The products from the insertion reaction with diazoket

NITROSOCHLORINATION REACTION OF SUBSTITUTED IMIDAZOLIN-2-ONES

Interaction of nitrosyl chloride with 1-arylimidazolin-2-ones in methanol leads to the formation of 4,5-dimethoxyimidazolidin-2-ones.Under similar conditions 1,5-diarylimidazolin-2-ones give 1,5-diaryl-4-oximino-5-alkoxyimidazolidin-2-ones.When the reacti
