5,5′-Thiobis(3-bromoisothiazole-4-carbonitrile)

open access: yesMolbank
The reaction of sodium 2,2-dicyanoethene-1,1-bis(thiolate) with bromine (2 equiv.) in CCl4 gave 3,5-dibromoisothiazole-3-carbonitrile and 5,5′-thiobis(3-bromoisothiazole-4-carbonitrile) in 7% and 18% yields, respectively.

Borylcyclopropanes: Synthetic Strategies and Applications

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...
