Carbamoyl chlorides are important intermediates, both in the research laboratory and in industrial scale syntheses. The most studied and used are the disubstituted derivatives, incorporating either aryl or alkyl groups (Ar₂NCOCl or R₂NCOCl). Sometimes, the groups are tied back to give a ring and

We have developed a novel and simple protocol for the direct incorporation of a difluoromethyl (CF2 H) group into alkenes by visible-light-driven photoredox catalysis. The use of fac-[Ir(ppy)3 ] (ppy=2-pyridylphenyl) photocatalyst and shelf-stable Hu's reagent, N-tosyl-S-difluoromethyl-S-phenylsulfo

… The solvolytic dissociation reaction rate constants of the Zn<SUP>II</SUP>–hscf complex ([ZnL]<SUP>3−</SUP>) (<I>k</I><SUB>d</SUB>) in the pH range of 6.4 to 8.0 were determined with a CE-based dissociation kinetic analysis method. …
a chemical reaction in which the solvent, such as water or alcohol, is one of the reagents and is present in great excess of that required for the reaction. Solvolytic reactions are usually substitution reactions-i.e., reactions in which an ...
