A silver-catalyzed dibromotrifluoromethoxylation of terminal alkynes has been reported, which provides the corresponding 1,1-dibromo-2-(trifluoromethoxy)alkenes in good yields and high regioselectivity under mild reaction conditions. The reaction exhibits a broad substrate scope and applies to late-stage trifluoromethoxylation of complex small mols. Moreover, the products can be further modified, which provides a convenient method for the synthesis of compounds containing the OCF3 group. And (1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6) was used in the research process.
(1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6 Electric Literature of C10H13ClO3) is a chiral derivatizing agent. It can be prepared by reacting (-)-(1S,4R)-camphanic acid with thionyl chloride.
