An unprecedented arylboration of unactivated terminal alkenes, featuring 1,n-regioselectivity, has been achieved by nickel catalysis. The nitrogen-based ligand plays an essential role in the success of this three-component reaction. This transformation displays good regioselectivity and excellent functional-group tolerance. In addition, the incorporation of a boron group into the products provides substantial opportunities for further transformations. Also demonstrated is that the products can be readily transformed into pharmaceutically relevant molecules. Unexpectedly, preliminary mechanistic studies indicate that although the metal migration favors the alpha-position of boron, selective and decisive bond formation is favored at the benzylic position.

The potential energy surfaces of the oxidation of three model heterocyclic organic sulfides dibenzothiophene (DBT), 4-methylbenzothiophene (MDBT) and 4,6-dimethyldibenzothiophene (2MDBT) were examined using HCO3H as oxidants adopting MP2, omegaB97X-D, M06-2X and B3LYP methods at 6-311+G (d,p) level. The stationary points on the potential energy surfaces for the first and second oxidation reaction were fully optimized and characterized. The natural orbital population analysis (NPA) was also performed to understand the charge distribution. The calculated results may contribute to understanding the reaction mechanism of the ODS of refractory DBT sulfides.

Photochromic diarylethenes have been widely used in many fields. However, their cyclization process must be induced by UV light. In this article, a simple strategy is developed by extending pi-conjugation with electron donating groups. The modified dirylethene derivative can photocyclolize under 405-nm light with a good photochromic efficiency. Meanwhile, its absorption and moderate fluorescence can be switched effectively in both directions by visible lights (405 and 520 nm, respectively) in different solutions and in living cells. We believe that this simple method will become a versatile strategy for developing various dirylethylenes with visible-light photochromism.

Trifluoromethanesulfinyl chloride (CF3SOCl) has been introduced as a new reagent for C?H trifluoromethylthiolation of indoles, thiophenes, and ketones under catalyst-free conditions and in the absence of reductant. The disproportionation of CF3SOCl to CF3SO2Cl and CF3SCl provides two pathways for the trifluoromethylthiolation. Direct trifluoromethylthiolation with CF3SCl or trifluoromethylsulfoxidation with CF3SOCl is followed by reduction with CF3SOCl. This reagent can be used to functionalize benzothiophenes, benzofurans, and indenes under the promotion of Ag2CO3. It can also be used for trifluoromethylthiolation of thiols and benzeneselenols, and 1,2-bifunctional chlorotrifluoromethylthiolation of indoles, styrenes, and alkyenes. The method can also be extended for difluorometylthiolation reactions using CF2HSOCl.
