�ؼ���� DMAP �� DMAP

Abstract�� Several new bisphosphorylation(phosphonylation) compounds have been prepared by phosphorylation of ��-aryl-��-nitroethylphosphonates under the lower tempera-ture,weaker base condition and in the presence of DMAP.The catalytic mecha-nism of DMAP have been studied in detail.All new compounds have been chara-cterized by IR and HNMR,some of them were also confirmed by mass spectrum or elemental analysis.
