Abstract
Trisulfide unit is widely found in natural products and has garnered attention due to the unique pharmacological and physiochemical properties. However, despite limited progress, widely applicable approaches for constructing unsymmetrical trisulfides have so far remain scarce. In this work, an easy-to-prepare, solid-state and scalable reagent, S-substituted sulphenylthiosulphate, has been developed for the divergent synthesis of unsymmetrical trisulfides. Alkyl electrophile substrates, including bromides, chlorides, iodides and tosylates, with diverse substituents are smoothly converted to the corresponding trisulfides with S-substituted sulphenylthiosulphates and thiourea as another sulfur source. Furthermore, the late-stage modification of drug molecules was successfully achieved through this method.

Abstract
The combining use of BnSCF2D, mCPBA and Tf2O serves as an efficient multi-component reagents system (MCRS) for the synthesis of deuteriodifluoromethylthiolated isocoumarins-1-imines/isocoumarins via intramolecular cyclization/deuteriodifluoromethylthiolation of 2-alkynylbenzamides/2-alkynylbenzoates. The approach features the generation of the crucial reactive electrophilic sulfonium salt through a sequence process involving the oxidation of BnSCF2D by mCPBA followed by Tf2O promoted activation.

Abstract
A new, stable and scalable reagent based on a sulfoxide skeleton for direct deuteriodifluoromethylthiolation has been developed. The reagent displays excellent reactivities toward Tf2O promoted C-H deuteriodifluoromethylthiolation of electron-rich arenes, indoles, alkenes, and intramolecular lactonization of 2-alkynylbenzoates. Moreover, high deuteration rates and good to excellent yields were achieved under metal-free reaction conditions. As a result, a wide range of deuteriodifluoromethylthilolated compounds were prepared, enabling further applications in drug discovery.

Abstract
A direct electrophilic difluoroalkylthiolation reaction of indole derivatives and other electron-rich heterocycles using methyl 2,2-difluoro-2-(chlorsulfonyl)acetate (ClSO2CF2COOMe) derived from Chen's reagent (FSO2CF2COOMe) is described. The ester group in the product can be further utilized in subsequent versatile transformations. The reactions provide good yields of the corresponding difluoroalkylthiolation products and exhibit high functional group compatibility. It is expected to serve as an alternative and practical protocol for difluoroalkylthiolation of various heterocycles.

Abstract
A practical method for the synthesis of 2,2-difluorinated 2,3-dihydrofurans has been established via the [4 + 1] annulation of enaminones and BrCF2CO2Et with Na2CO3 promotion. This new protocol does not employ any transition metal reagent and enables the annulative difluoromethylation by the partial cleavage of the C═C double bond. In addition, the further treatment with hydrochloric acid in one pot leads to β-keto enoic acids (4-oxo-2-butenoic acids) via a formal enaminone C-N carboxylation.

Abstract
Herein we describe an efficient construction of HCF2Se and HCF2S groups by tandem substitutions between alkyl bromides and a reagent system consisting of MSeCN (or MSCN) and Ph3P+CF2H Br-. The tandem process occurs via the first nucleophilic substitution of alkyl bromides by -SeCN (or -SCN) and the subsequent nucleophilic difluoromethylation.

Abstract
Deuteriodifluoromethythio (SCF2D) and deuteriodifluoromethyl (CF2D) are important functional groups in pharmaceutical and agrochemical compounds, and the introduction of these functional groups remains a challenging. We herein report a robust reagent for deuteriodifluoromethylthiolation and deuteriodifluoromethylation. Its potentials were successfully showcased by deuteriodifluoromethylation and deuteriodifluoromethylthiolation of indoles with high-level deuterium incorporation. The reagent also has potential for deuteriodifluoromethylation and deuteriodifluoromethylthiolation of wide range of other natural or synthetic bioactive molecules.
