Peculiar Features of the Willgerodt–Kindler Reaction of 1-Adamantylpropan-2-one and Its Derivatives
摘要:
The Willgerodt-Kindler reaction of 1-(1-adamantyl)propan-2-one and its derivatives was studied by gas chromatography-mass spectrometry. The reaction time was found to be 3-4 times longer than in the case of alkyl aryl ketones due to considerable steric hindrances in the molecules of adamantyl ketones. The use of diglyme as solvent and sodium butyl xanthate as catalyst significantly shortened the reaction time and improved the yield to 92%.

the preparation of aryl xanthates and aryl dithiocarbamates from functionalized dibenzothiophenium salts via a photoactivated electron donor–acceptor complex. This mild, metal-free method is operationally simple and has a broad substrate scope and potential utility for late-stage functionalization of natural products and pharmaceuticals. Finally, this method also has redefined the substrate scope and
