Electrocatalytic synthesis of α,α-gem-dihalide ketones from α-mono-halide ketones and unexpected dimer condensation

Abstract

A novel, environmentally-friendly method has been developed to prepare α,α-gem-dihalide (F, Cl, and Br) ketones from α-mono-halide ketones in an aqueous solution containing an alkali halide salt using an electrocatalytic...

Photocatalytic [4+2] cyclization of biomass furan into a cantharidin-like skeleton

“…7 shows the Stern–Volmer plot spectroscopy. 43 The electron transfer in the quenching process was analyzed using eqn (1):where I o is the luminescence intensity in the absence of a quencher, I f is the fluorescence intensity, and K sv represents the Stern–Volmer static quenching rate constant. The K sv was calculated as the slope of the Stern−Volmer lines.…”

Bioinspired Natural Shellac Dressing for Rapid Wound Sealing and Healing

“…Phospholipid is an important component of cell membranes and is a basic structural unit for the formation of various biological tissues. , As shown in Figure A, a phospholipid is an amphiphilic molecule with hydrophobic lipid ends and hydrophilic phosphate or organic amine groups, and most importantly, the shellac monomer has a similar molecular structure (Figure S20). We hypothesized that perhaps it was this molecular similarity that allowed shellac monomer to easily penetrate cell membranes and promote wound healing, and therefore, the binding interactions between shellac and phospholipid were simulated and investigated. – …”

Scalable selective electrochemical oxidation of sulfides to sulfoxides

“…The radical clock experiment showed that the vinyl cyclopropane derivative F achieved the rupture of the three-membered ring G , which was detected through HPLC-MS analysis (see the ESI† for details, Scheme 5e), which confirmed the existence of the chlorine radical during the reaction. 19 The fluorescent probe response test of ClO − showed that a trace amount of ClO − ( ca. 2.5 × 10 −4 mol L −1 ) was generated in the transformation (see the ESI† for details).…”
