The design and synthesis of β-trifluoromethylenol phosphates as potential insecticides

Ding, Yixiang,Huang, Xiaogen

, p. 304 - 308 (2007/10/03)

A new group of compounds, β-trifluoromethylenol phosphates [(RO)2P(O)OCR=CHCF3], has been designed and prepared by several methods. Some of them showed good insecticidal activities. In the molecular structure, the designed leaving group can rearrange to a powerful electrophilic agent, β,β-difluorovinyl ketone, which would be a potential enzyme inhibitor.
