Wang, Bin; Yan, Zicong; Liu, Liyan; Wang, Jiawei; Zha, Zhenggen; Wang, Zhiyong published the artcile< TBN-mediated regio- and stereoselective sulfonylation & oximation (oximosulfonylation) of alkynes with sulfonyl hydrazines in EtOH/H2O>, Synthetic Route of 2725-82-8, the main research area is sulfonyl aryl ketoxime regioselective stereoselective preparation; tandem sulfonylation oximation terminal aryl alkyne arylsulfonylhydrazine butyl nitrite; byproduct radical inhibition tandem sulfonylation oximation alkyne arylsulfonylhydrazine; mechanism tandem sulfonylation oximation alkyne arylsulfonylhydrazine nitrite.
Terminal aryl alkynes such as phenylacetylene underwent regioselective and diastereoselective cascade sulfonylation and oximation reactions with arylsulfonyl hydrazides such as 4-MeC6H4SO2NHNH2 mediated by tert-Bu nitrite (TBN), hydrazine hydrate, and imidazole in 40:1 EtOH:H2O to yield (Z)-α-sulfonyl aryl Me ketoximes such as (Z)-4-MeC6H4SO2CH2C(:NOH)Ph. The mechanism was studied through identification of byproducts and radical inhibition and deuterium incorporation studies.
Green Chemistry published new progress about Alkynes, aryl Role: RCT (Reactant), RACT (Reactant or Reagent) (terminal). 2725-82-8 belongs to class bromides-buliding-blocks, and the molecular formula is C8H9Br, Synthetic Route of 2725-82-8.
