Ring-opening 1,3-halochalcogenation of cyclopropane dicarboxylates
Wallbaum, Jan,Garve, Lennart K. B.,Jones, Peter G.,Werz, Daniel B.
, p. 98 - 101 (2017)
Donor-acceptor cyclopropanes with two geminal carboxylic esters are reacted with chalcogenyl chlorides and bromides to afford ring-opened products bearing the halogen atoms in the 1-position, adjacent to the donor, and the chalcogenyl residue in the 3-pos
Sulfonyl halide synthesis by thiol oxyhalogenation using NBS/NCS – iPrOH

A rapid and facile method provides a general route to sulfonyl bromides/chlorides by the oxidation of thiols using NXS – ROH (X?=?Br,Cl, R?=?iPr) as an oxyhalogenation reagent. Control experiments suggest that the alcohol component is the source of oxygen. The proposed method enable the access to structurally diverse sulfonyl bromides and chlorides including challenging examples, inaccessible by other synthetic methods.
Design, synthesis and biological evaluation of sulfenimine cephalosporin sulfoxides as β-lactamase inhibitors
Zhang, Kai,Ding, Huai-Wei,Ju, Hao,Huang, Qi,Zhang, Li-Juan,Song, Hong-Rui,Fu, De-Cai
, p. 801 - 803 (2015/08/03)
Abstract A series of sulfenimine cephalosporin sulfoxide derivatives (7a-v) were designed, synthesized and evaluated for their inhibitory activity against TEM-1 and cephalosporinase in cell-free systems. Some of the tested compounds showed enhanced inhibi
" On-water " thiolysis of epoxides promoted by PhSZnBr
Propersi, Simona,Tidei, Caterina,Bagnoli, Luana,Marini, Francesca,Testaferri, Lorenzo,Santi, Claudio
, p. 671 - 676 (2014/01/06)
The synthesis of a new bench-stable and odorless zinc thiolate is here reported. The thiolysis of epoxides effected using this reagent showed a considerable rate acceleration of the reaction when effected in "on-water" conditions. In addition, the reactio
A SIMPLE PREPARATION OF SEVERAL NEW 2,3- AND 1,2,3-SUBSTITUTED BUTA-1,3-DIENES FROM 1,4-DICHLOROBUTYNE
Bridges, Alexander J.,Fischer, John W.
, p. 445 - 446 (2007/10/02)
Addition of (pseudo) halogens across the triple bond of 1,4-dichlorobut-2-yne, followed by a 1,4-elimination, provides a very simple preparation of ten novel butadienes.
SULFENYL CHLORIDES, XIV; THE REACTION OF ARYLTHIOSULFONATES WITH ARYLSULFENYL HALIDES
Lazar, J.,Vinkler, E.
, p. 171 - 174 (2007/10/02)
Utilizing partial results published earlier , the sulfenylation reaction of aromatic thiolsulfonates was investigated.Aromatic thiolsulfonates rapidly react with sulfenyl bromide in acetonitrile solution, whereas with sulfenyl chloride the splitting of the thiolsulfonate bond proceeds only in dimethylformamide and under forceful conditions.
