| 1,5,7-Triazabicyclo[4.4.0]dec-5-ene Usage And Synthesis |
| Chemical Properties | Light yellow crystalline | | Uses | 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. | | General Description | 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 and 1H NMR. | | Purification Methods | 1,5,7-Triazabicyclo[4.4.0]dec-5-ene crystallises from Et2O but readily forms white crystals of the carbonate. It is a strong base (see pK, i.e. about 100 times more basic than tetramethylguanidine). The picrate has m 220.5-222o (from EtOH). It forms the 5-nitro derivative m 14.5-160o that gives a 5-nitro nitrate salt m 100-101o (from EtOH/Et2O) and a 5-nitro picrate m 144-145o (from H2O) [McKay & Kreling Can J Chem 35 1438 1957, Schwesinger Chimia 39 369 1985, Hilpert et al. J Chem Soc, Chem Commun 1401 1983, Kamfen & Eschenmoser Helv Chim Acta 72 185 1989]. [Beilstein 26 III/IV 60.] |
