DOI: 10.1002/cssc.201803058
Abstract: Electrochemical 1,2-hydroxydifluoromethylation and C-H difluoromethylation of acrylamides were developed by using CF2 HSO2 NHNHBoc as the source of the CF2 H group. These electricity-powered oxidative alkene functionalization reactions do not need transition-metal catalysts or chemical… read more here.

DOI: 10.1002/cssc.202200367
Abstract: Herein, we report a method for iron-catalyzed, visible-light-induced hydrosilylation reactions of electron-deficient alkenes to produce value-added silicon compounds. Alkenes bearing functional groups with different steric properties were suitable substrates, as were derivatives of structurally complex… read more here.

DOI: 10.1021/acs.organomet.7b00545
Abstract: Tricarbonylruthenacyclopentanes were successfully synthesized by in situ reduction of RuCl3 with Zn-Cu/CO in the presence of N-vinylacetamides and electron-deficient alkenes such as ethyl acrylate, dimethyl fumarate, and dimethyl maleate. X-ray crystallography of the ruthenacyclopentanes revealed… read more here.
