Hydrazinolysis of the pentacarbonyl[alkyl- or aryl-(methoxy)carbene] complexes of W0 and Cr0 with both 1,1- and 1,2-disubstituted hydrazines affords the corresponding new hydrazinocarbenes 15–18, 21 and 22, and the presence of LiCl in the reaction medium greatly increases their yields.
五碳基[烷基或芳基-(甲氧基)碳烯]的W0和Cr0复合物与1,1-和1,2-取代的肼进行氢肼解反应,得到相应的新肼基碳烯15-18、21和22,并且在反应介质中加入LiCl显著提高了它们的产率。
