Abstract
Photoinduced cyclization of 2,3-allenoic acids with sulfonyl chloride providing an efficient synthesis of 4-sulfonylated furan-2(5H)-ones under mild reaction conditions has been achieved. The reaction enjoys a high chemoselectivity and tolerates a wide range of functional groups. The catalytic cycle has been validated through control experiments, cyclic voltammetry studies, and Stern-Volmer quenching studies.

Abstract
A rare type of demethylenative intramolecular cyclization of 1,7-enynes to access quinoline-2-(1H)-ones has been successfully developed under the catalysis of P/N-heteroleptic Cu(I)-photosensitizers. Preliminary mechanistic experiments revealed that the key to the success of this protocol lay in the α-amino radical addition-triggered tandem process of intramolecular radical cyclization/1,5-HAT/β-fragmentation. This protocol provides a new avenue for the deconstructive cyclization of alkene derivatives.

Abstract
The use of readily available and diverse sulfamoyl chlorides for synthesizing sulfonamide compounds presents an intriguing, yet significantly underexplored strategy. Activating sulfamoyl chlorides via single-electron reduction poses challenges due to their high reduction potential. Alternatively, the SO2-Cl bond in sulfamoyl chlorides could be readily cleaved by XAT. However, the existing methodologies have been limited to either the use of photocatalyst or the monofunctionalization of activated alkenes. Here, we report a regioselective sulfamoyl-oximation of alkenes by involving the activation of sulfamoyl chlorides through a HAT and XAT relay strategy in a photocatalyst-free way. The key to this success lies in the dual roles of tert-butyl nitrite (TBN), which not only serves as the source of oximes but also acts as the HAT reagent to generate the crucial XAT reactive species. The exclusion of metal catalysts or photosensitizers for utilizing light energy renders this protocol versatile and universally applicable for synthesizing a broad range of structurally diverse oxime-containing alkyl sulfonamides.

Abstract
A metal-free photosensitized 1,2-imino-sulfamoylation of olefins by employing a tailor-made sulfamoyl carbamate as the difunctionalization reagent has been established. This protocol exhibits versatility across a broad substrate scope, including aryl and aliphatic alkenes, leading to the synthesis of diverse β-imino sulfonamides in moderate to good yields. This method is characterized by its metal-free reaction system, mild reaction conditions, excellent regioselectivity, and high atom economy, serving as a promising platform for the preparation of β-amino sulfonamide-containing molecules, particularly in the context of drug discovery.

Abstract
Alkyl sulfonamides are an important class of bioactive molecules. Historical syntheses have relied on multistep sequences incorporating harsh reaction conditions. Photochemical methods have been limited to hydrosulfamoylation, installing only one substituent across an olefin. Herein, radical/polar crossover (RPC) is used to establish the first multicomponent 1,2-difunctionalization reaction incorporating a sulfonamide moiety and a second reaction partner. This protocol, exemplified on a range of olefins, utilizes various commercial sulfamoyl chlorides and organotrifluoroborates as coupling partners.
