综述了有机硒、碲化合物的合成及其在高选择性合成反应中的反应。低价硒、碲化合物具有良好的还原选择性，可用于多种碳－氢键的形成，碲叶立德和α－芳硒基取代的胂叶立德均可发生Ｗｉｔ－ｔｉｇ 型反应，是形成碳－碳双键的重要方法。将锆、锡、卤素、硼等金属或杂原子导入到有机硒、碲分子中可以形成新型双功能团试剂，继而在过渡金属催化下可以开发多种形成碳－碳单键的偶联反应。 The synthesis of organic selenium and tellurium compounds and their reactions in high selectivity synthesis reactions are reviewed. Low-valent selenium and tellurium compounds have good reduction selectivity and can be used for the formation of various carbon-hydrogen bonds. The Wit-tig type reactions of both telluride ylide and α-arylene selenium-substituted arsonium ylides can result in the formation of carbon-carbon Important method of double bond. The introduction of zirconium, tin, halogen, boron and other metals or heteroatoms into organic selenium and tellurium molecules can form novel bifunctional reagents, and then a variety of coupling reactions can be developed under the transition metal catalysis to form carbon-carbon single bonds.
