aryltriazenes using Brønsted ionicliquid as a promoter has been developed for the first time. Many N-heterocyclic azo compounds were synthesized in good to excellent yields at roomtemperature under an open atmosphere. Notably, the promoter 1,3-bis(4-sulfobutyl)-1H-imidazol-3-ium hydrogen sulfate could be conveniently recycled and reused with the same efficacies for at least four cycles.
A new and efficient approach adopting copper-catalyzed cross-coupling of sulfonyl hydrazides with aryltriazenes has been developed to synthesize aryl sulfones using Brønsted acidic ionic liquid as promoter under ambient conditions. The process employs stable and easy to handle reacting partners, and is endowed with broad substrate scope.

cross-coupling reaction of 1-aryltriazenes with arylboronicacidscatalyzed by a recyclable polymer-supported Pd-NHC complex catalyst has been realized for the first time. The polymer-supported catalyst can be re-used several times still retaining high activity for this transformation. Various aryltriazenes were investigated as electrophilic substrates at roomtemperature to give biaryls in good to excellent

[reaction: see text] Aryltriazenes are directly coupled with areneboronic acids in the presence of a catalytic amount of Pd(2)(dba)(3) and P(tBu)(3) together with 1 equiv of BF(3).OEt(2) in DME to afford the corresponding biaryl products in up to 98% yield. A carbonylative cross-couplingreaction under a carbon monoxide atmosphere is also found to give the corresponding diaryl ketone with a similar
