Recent advances in the chemistry of chlorosulfonyl isocyanate: a review

Facile modification of phosphole-based aggregation-induced emission luminogens with sulfonyl isocyanates

“…CSI 5a is the most reactive isocyanate known. 38 In addition to the well-known cycloadditions, a wide variety of nucleophilic addition and substitution reactions are possible, making CSI a powerful reagent. 39 When phosphole oxides 1-4 were treated with a solution of 5a, we could observe a specic reaction behavior.…”

A New family of Sulfamidophosphonates Derivatives: Microwave‐Accelerated Multicomponent Synthesis, Characterization and X‐Ray Crystallographic Study**

“…But surprisingly, in the literature, very few works have been reported on the synthesis of bifunctional compounds containing both sulfamide and phosphonate moieties [52,53] . In this context, our laboratory group research based on the development of novel biomolecules by effective and simplified procedures [54,55] . In 2015, Belhani et al .…”

“…[52,53] In this context, our laboratory group research based on the development of novel biomolecules by effective and simplified procedures. [54,55] In 2015, Belhani et al reported a simple and efficient method for the synthesis of a novel α-sulfamidophosphonates ultrasound activation and solvent-free conditions with excellent yields. [56] Recently, Guerfi et al described novel α-sulfamidophosphonates analogues of fotemustine by an efficient synthesis using ultrasound under solvent free conditions.…”

N-Chlorosulfonyl carbamate-enabled, photoinduced amidation of quinoxalin-2(1H)-ones

“…Bearing both isocyanate and sulfonyl chloride functionalities simultaneously, CSI could facilely react with an array of nucleophiles such as amines and alcohols, giving various sulfamide derivatives. 6 And one of the most attractive and synthetically useful utilizations of sulfamide derivatives has been demonstrated in the preparation of Burgess reagent, 7 a widely used dehydrating reagent. Interestingly, despite the clearly defined reactivity with nucleophiles, the open–shell chemistry of CSI derivatives has been rarely explored.…”
