Cobalt-catalyzed amination of triazoles with dioxazol-5-ones through triazole-directed ortho C H activation
摘要:
Cobalt-catalyzed reactions of triazoles and dioxazol-5-one involving nitrene transfer were described. A number of amidated 1,2,3-trizole derivatives have been obtained in moderate to excellent yields. (C) 2016 Elsevier Ltd. All rights reserved.

science. In this paper, rhodium(III)-catalyzed triazole-directed alkylation reactions of arenes using diazo compounds as the alkylating agents are described. A number of polysubstituted arenes were provided from easily available materials in good yields under mild conditions. The reactions proceed via triazole-directed ortho C–H bond activation and subsequent carbeneinsertion originating from diazo

Silver(I)‐catalyzed click chemistry: Substituted 1,2,3‐triazoles are versatile intermediates with an expanding array of applications. The discovery and application of a general AgI‐catalyzed azide–alkyne cycloaddition reaction (AAC) leading to 1,2,3‐triazoles is reported. The synthesis of a stable, well‐defined AgI complex of type [AgI(L2)(OAc)] is described, along with the unprecedented ability of
