1,5,7-三氮杂双环[4.4.0]癸-5-烯，一种双环胍碱，已被发现是迈克尔和迈克尔型反应的优良催化剂。它可与拉沙里菌素酸形成1：1复合物，并且其晶体结构已通过X射线衍射、FT-IR光谱和1H NMR进行研究。 应用 1,5,7-三氮杂双环[4.4.0]癸-5-烯可用作酯氨解过程的有机催化剂。它可以用作催化剂，用于在各种活化的烯烃中直接加入P（O）-H键（二烷基亚磷酸酯和二苯基亚膦酸酯）。聚合物负载的1,5,7-三氮杂双环[4.4.0]癸-5-烯（PTBD）可用作碱和试剂清除剂，以用于由酚和烷基或芳基卤化物合成芳基醚。 1,5,7-Triazabicyclo[4.4.0]dec-5-ene, a bicyclic guanidine base, has been found to be an excellent catalyst for Michael and Michael-type reactions. It forms 1:1 complex with lasalocid acid and crystal structure of the complex has been studied by X-ray diffraction, FT-IR spectroscopy and1H NMR.1,5,7-Triazabicyclo[4.4.0]dec-5-ene may be used as organocatalyst for aminolysis of esters. It may be used as catalyst for direct addition of P(O)-H bonds (dialkyl phosphites and diphenyl phosphonite) across various activated alkenes. Polymer supported 1,5,7-triazabicyclo[4.4.0]dec-5-ene (PTBD) was used as a base and a reagent scavenger for the synthesis of aryl ethers from phenols and alkyl or aryl halides.
