Conclusions
-
1.
Perfluoromethaerylic acid derivatives when reacted with trialkyl phosphites give stable adducts that contain a pentacoordinated phosphorus atom, and specifically are substitutedα-fluorovinyltrialkoxy-fluorophosphoranes.
-
2.
The phosphoranes obtained from perfluoromethacrylic acid esters and trialkyl phosphites are cleaved when heated, in which connection the products of the Arbuzov reaction are not formed, but instead alkyl difluorophosphites and the esters ofα-trifluoromethyl-β,β-dialkoxyacrylic acids.
