Electrochemical reductions of monothiobenzils in the presence of either aroyl or carbonimidoyl dichlorides were carried out, yielding products with sulfur retention. Electrolyses in the presence of aroyl chlorides led to previously unknown (Z)-α-aro

X-ray structure determinations of mesitylene- and dimesitylmethane-derived compounds bearing bromomethyl units (compounds 1–3) show that the crystal packing of the molecules is characterized by the presence of C–H⋯Br interactions, such as BrCH2

Oxidative radical cyclizations starting from easily accessible N-allylic β-alanine esters are reported. Deprotonation generates the corresponding enolates, which are transformed efficiently into α-ester radicals by single electron transfer mediated

Cathodic reductions of 2,2′-furils in the presence of N-arylcarbonimidoyl dichlorides lead to 2-arylimino-4,5-di(2-furyl)-1,3-dioxoles in high yields, along with minor amounts of (E)-1,2-di(2-furyl)vinylene bis(N-arylchloroformimidates). HF and B3L
