The author mentioned the following in the article:
A simple and efficient protocol for para-selective C-H amination of 1-naphthylamide derivatives under silver catalysis was described. This reaction system proceeded without the help of directing group and a broad range of substrates were proved to be well tolerated. In addition, control experiments suggested that this reaction might not proceed via a single-electron-transfer process.(1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6) were involved in the experimental procedure.
(1S)-4,7,7-Trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carbonyl chloride(Chunks or pellets) (cas: 39637-74-6 COA of Formula: C10H13ClO3) is a chiral derivatizing agent. It can be prepared by reacting (-)-(1S,4R)-camphanic acid with thionyl chloride.
