A facile and sustainable protocol for the thiolation of hydrazones with sodium sulfinates has been developed in the presence of CuBr 2 and DBU in DMF to afford diverse benzylic thioethers. Control experiments reveal a radical pathway involving a thiyl radical as a key intermediate.
A practical
approach for the regioselective synthesis of 3-arylthioindoles
has been accomplished using a combination of 1-aryltriazene/CS2 as a new sulfenylation source. The methodology employs molecular
iodine as a catalyst and is compatible with a variety of structurally
diverse reactants.
A concerted metallophotoredox catalysis
has been realized for the
efficient decarboxylative functionalization of α,β-unsaturated
carboxylic acids with aryl iodides in the presence of perylene bisimide
dye to afford 1,2-diketones.
An efficient visible-light-induced synthesis of trans-oxiranes has been accomplished via decarboxylative stereospecific epoxidation of trans-cinnamic acids by aryldiazonium salts using CuCl, eosin Y, TBHP, and DBU. The reaction is facile, straightforward, and endowed with good functional group tolerability and a good substrate scope.
A facile synthesis of α-carbonyl sulfones has been accomplished by the cross-coupling of α-aryl-α-diazoesters with sulfonyl hydrazides in the presence of CuI and DBU. The reaction employs inexpensive and bench...
An efficient copper‐catalyzed synthesis of N‐arylated amines has been developed via cross‐coupling of amines with aryl triazenes. The methodology is endowed with broad substrate scope, high yield, and significant functional group tolerance.
An approach to unsymmetrical thiosulfonates has been developed using sulfenylation of sodium sulfinates by arenediazonium tetrafluoroborate/CS 2 combination with io-dine as catalyst. The reaction is simple, high yielding, scalable, and proceeds smoothly with good substrate scope and functional group tolerance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
