Photoinduced C(sp3)-H borylation of alkanes mediated by copper(II) chloride.

Alkyl boronic acid and its derivatives are important motifs in organic synthesis and pharmaceuticals. Herein, we report a photoinduced, CuCl2 mediated C(sp3)-H borylation of unactivated alkanes. This protocol features mild reaction conditions, readily available reagents, and gram-scalability.

Electrochemical Trifluoromethylation of Thiophenols with Sodium Trifluoromethanesulfinate.

We developed an electrochemical trifluoromethylation of thiophenols without the use of metal catalysts and oxidants. This reaction features mild reaction conditions, readily available substrate, as well as moderate to good yields. In addition, this protocol can be easily scaled up with moderate efficiency.
