Abstract
1,5-Diazabicyclo[4,3,0]nonane was prepared via1,5-diazabicyclo[4,3,0]nonene(DBN) reduced with LiAlH 4 at 55 ℃ for 9 h.The yield and purity of the product can achieve 87.9% and 95%,respectively.Then the novel amidine photobase generators was synthesized through the reaction of 1,5-diazabicyclo[4,3,0]nonane with corresponding benzyl compounds.The result indicated that the yield and purity was up to 89.92% and 95.6%,respectively.The intermediates and products were charactered by HPLC,LC-MS and 1 HNMR.
