| | 1,3,4,6,7,8-HEXAHYDRO-1-METHYL-2H-PYRIMIDOL[1,2-A]PYRIMIDINE Usage And Synthesis |
| Chemical Properties | Colorless liquid | | Uses | 7-Methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene may be used in microwave-promoted, palladium-catalyzed C-N bond-forming reactions with aryl/heteroaryl nonaflates and amines. It may be used as strong base to investigate the podand solvents, tris(oxaalkyl)phenylsilanes and tris(oxaalkyl)phosphates. | | General Description | 7-Methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene is a soluble amine base. It forms 1:1 complexes with 4-nitrophenyl[bis(diethylsulfonyl)]methane and phenyl[bis(diethylsulfonyl)]methane and their structures have been studied by FT-IR, 1H NMR and PM5 semiempirical methods. Catalytic performance of 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene for the transesterification of rapseed oil with methanol has been investigated. |
