Highly chemo-, regio-, and stereoselective syntheses of novel organoselenium compounds from selenium dichloride or dibromide and unsaturated ethers are described. The reactions of selenium dichloride with allyl and propargyl phenyl ethers afford either annulated products or bis-adducts depending on the conditions. The first examples of annulation of 3-chloromethyl- and 3-chloromethylene-2,3-dihydro-1
描述了由二氯化硒或二溴化物和不饱和醚高度化学合成,区域选择性和立体选择性的新型有机硒化合物。根据条件,二氯化硒与烯丙基和炔丙基苯基醚的反应可提供环状产物或双加合物。报道了3-氯甲基-和3-氯亚甲基-2,3-二氢-1,4-氧杂亚硒酸酯与苯环环合的第一个实例。
