A mild silver-mediated cascade trifluoromethylthiolation/cyclization of unactivated alkenes with readily available AgSCF₃ as the trifluoromethylthiolating reagent has been explored.

A general and efficient photochemical strategy for difluoromethylation/radical cascade cyclization of alkynes with sodium difluoromethylsulfinate (NaSO₂CF₂H) has been disclosed.

A novel protocol for the construction of diverse dehydro-2-naphthol-1-sulphides and naphtha-oxathiane derivatives via in situ [4 + 2] cycloadditions of β-naphtha-1-thioquinones generated from 2-naphthols and DAST has been developed.

A mild and efficient Cu-assisted trifluoromethylthiolation/radical cascade cyclization of alkynes with readily available and stable AgSCF ₃ as the trifluoromethylthiolating reagent has been disclosed.

The first metal-free method for alkylation of quinoxalinones using cheap and stable aryl alkyl ketones as nucleophilic alkylation reagents is reported.

An efficient copper-catalyzed cascade difunctionalization of N-allyl anilines toward the synthesis of silylated indolines using commercially available silanes has been reported.

Here, complex 1 ([Ru(bpy)₂(hpip)]²⁺–MV²⁺) and CB[8] can form a stable 1 : 1 inclusion complex in aqueous solution, resembling a U-shaped conformation. Upon light irradiation, two complex 1 were reversibly locked through the formation of a MV˙⁺ radical dimer that is stabilized in the cavity of CB[8] with Ru complexes as blockers, in which complex 1 was transformed from a U-shaped conformation to a interlocked complex. This study provided a feasible strategy for the fabrication of a photo-driven supramolecular machine resembling a “lock”.

A transition‐metal‐free cross‐coupling of arylsilanes with DAST (diethylaminosulfur trifluoride) reagent has been developed. A number of aromatic sulfinamides were obtained in reasonable yields (15%‐87%). Notable advantages of this method include easy operation, mild reaction conditions and wide substrate scope.

A novel and efficient method for the generation of alkyl radicals and the alkylation of quinoline and pyridine derivatives under mild conditions has been developed. This strategy allows the direct alkylation of heteroaromatics in the absence of an external oxidant. A preliminary mechanistic study suggests that the present reaction probably proceeds via an intermolecular HAT process.
