The behaviour of the acrylonitrile 1 toward different types of phosphorus ylides such as alkoxycarbonyl- 2a,b and β-keto-alkylidene phosphoranes 2c-e as well as arylidenephosphorane 3 has been studied. The reactions take different pathways leading to unusual products, depending only on the nature of the substitutents of ylides used. All reactions proceed only in the presence of a base whereby a variety
已经研究了丙烯腈1对不同类型的磷化磷,例如烷氧基羰基-2a,b和β-酮亚烷基膦烷2c-e以及亚芳基膦烷3的行为。这些反应采用不同的途径产生不寻常的产物,这仅取决于所用酰化物的取代基的性质。所有反应仅在存在碱的情况下进行,其中存在各种1,3,3-苯并噻唑基-[1,2- x ]稠合的化合物,例如6、16和18。环丙烯15和环丙烷19衍生物以及不同类型的新化合物:7、10和分离并根据化学和物理证据确定12a,b。
