Reactive organosulfenyl chlorides (ArSCl) or selenenyl chlorides (ArSeCl), generated in situ from the reaction of PhICl2 with diorganyl disulfides or diselenides, enable the intramolecular oxidative cyclization/chalcogenylation of β,γ-unsaturated oximes, leading to the formation of a series of chalcogenylated isooxazolines in good to excellent yield.
PhICl 2与二有机二硫化物或二硒化物反应原位生成的反应性有机亚硫酰氯 (ArSCl) 或硒酰氯 (ArSeCl),使 β,γ-不饱和肟分子内氧化环化/硫属元素化,形成一系列硫属化异恶唑啉的产率非常好。
