  摘要：

  在水相介质中，在三氟甲磺酸钪作为路易斯酸催化剂的存在下，多种苯甲酰肼与四烯基锡的烯化反应在室温下顺利进行，以高产率生成相应的同烯丙基胺衍生物。醛、苯甲酰肼和四烯基锡的三组分反应也可以在相同介质中通过三氟甲磺酸钪催化。此外，还开发了一种利用这些反应制备恶唑啉酮衍生物的简单方法。

  摘要：

  氧-羰基异构体Sydnone（V）已经通过1-苯酰-1-甲基-肼盐酸盐（VII）和光气合成。异Sydnone V本身与光气反应形成2-氯-5-苯基-1,3,4-噁二唑（VI），一种新的取代1,3,4-噁二唑。盐酸盐VII的热重排发生在200°C，形成1-苯酰-2-甲基肼，它与光气形成异构体XI。讨论了这些转化的一些机理途径。
