چکیده
A four-component reaction of aryldiazonium tetrafluoroborates, sulfur dioxide, 1,2-dibromoethane, and hydrazines under metal-free conditions is described, providing a novel and efficient approach to 2-arylsulfonyl hydrazones. This transformation proceeds smoothly via insertion of sulfur dioxide under mild conditions with good functional group tolerance.

A palladium-catalyzed three-component coupling of arylboronic acids, sulfur dioxide and hydrazines.
A novel and efficient route to aryl N-aminosulfonamides via a palladium-catalyzed three-component coupling of arylboronic acids, sulfur dioxide and hydrazines in the presence of a balloon of dioxygen is reported. The reaction proceeded smoothly under mild conditions and DABCO·(SO(2))(2) was used as the source of sulfur dioxide.
متن کاملSynthesis of 1-(2,3-dihydrobenzofuran-3-yl)-methanesulfonohydrazides through insertion of sulfur dioxide.
A three-component reaction of 2-(allyloxy)anilines, sulfur dioxide and hydrazines under mild conditions is developed, which gives rise to 1-(2,3-dihydrobenzofuran-3-yl)-methanesulfonohydrazides in good yields. This radical process involves an intramolecular 5-exo-cyclization and insertion of sulfur dioxide.
متن کاملA palladium-catalyzed reaction of aryl halides, potassium metabisulfite, and hydrazines.
Aryl N-aminosulfonamides could be easily produced via a palladium-catalyzed coupling of aryl halides, potassium metabisulfite, and hydrazines. Potassium metabisulfite is an excellent equivalent of sulfur dioxide in the reaction of palladium-catalyzed aminosulfonylation.
متن کاملChiral anion phase transfer of aryldiazonium cations: an enantioselective synthesis of C3-diazenated pyrroloindolines.
Herein is reported the first asymmetric utilization of aryldiazonium cations as a source of electrophilic nitrogen. This is achieved through a chiral anion phase-transfer pyrroloindolinization reaction that forms C3-diazenated pyrroloindolines from simple tryptamines and aryldiazonium tetrafluoroborates. The title compounds are obtained in up to 99% yield and 96% ee. The air- and water-tolerant...
متن کاملPyridine-promoted dediazoniation of aryldiazonium tetrafluoroborates: Application to the synthesis of SF5-substituted phenylboronic esters and iodobenzenes
Pyridine promotes dediazoniation of aryldiazonium tetrafluoroborates. The formed aryl radicals were trapped with B2pin2, iodine, or tetrahydrofuran to afford boronic esters, iodobenzenes and benzenes, respectively. The application to the synthesis of (pentafluorosulfanyl)phenylboronic esters, iodo(pentafluorosulfanyl)benzenes and (pentafluorosulfanyl)benzene is shown.
