developed for the hydroamination of alkynes by 1,1-disubstituted hydrazines. The catalyses are facile with terminal alkynes and some internal alkynes. If the hydrazine bears an aryl group, Fischer cyclization can occur in a one-pot procedure. In addition, reactions with acetylene to produce a plethora of hydrazones are described. Catalytic reactions involving acetylene and substituted hydrazines are complete
[反应:见正文]已开发出两种易于制备的催化剂,用于1,1-二取代肼对炔烃的加氢胺化作用。该催化剂容易与末端炔烃和一些内部炔烃反应。如果肼带有芳基,则可以一锅法进行费歇尔环化。另外,描述了与乙炔的反应以产生大量的hydr。涉及乙炔和取代肼的催化反应在室温和1个大气压下于不到2小时内即可完成。
