The titanium-nitrogen complex 1, [TiNMg2Cl2·THF] prepared from TiCl3 or TiCl4 and Mg in THF under nitrogen reacts with acid chloride to give amide and/or imide. The cyclic imides were obtained by the reaction of titanium-isocyanate complex 3, [3THF·Mg2Cl2OTiNCO], made from titanium-nitrogen complex 1 and carbon dioxide, and the corresponding cyclic acid anhydrides. Benzoxazone derivatives afforded
由TiCl 3或TiCl 4和Mg在THF中在氮气下制得的钛-氮络合物1 [TiNMg 2 Cl 2 ·THF]与酰氯反应生成酰胺和/或酰亚胺。通过由钛-氮配合物1制成的异氰酸钛配合物3,[3THF·Mg 2 Cl 2 OTiNCO]和二氧化碳与相应的环状酸酐的反应获得环状酰亚胺。苯并恶唑酮衍生物以类似的方法得到相应的喹唑啉衍生物。这些结果表明,分子氮通过钛氮配合物掺入有机化合物中。
