Interaction of triethyl phosphite with 3-fluoropropanoyl chloride: the concurrent formation of 1:2 and 2:1 reaction products
Abstract
The major products of the interaction between triethyl phosphite and 3-fluoropropanoyl chloride at room temperature are diethyl (E)-1-(3-fluoropropanoyloxy)-3-fluoroprop-1-enylphosphonate 3 and diethyl 1-(diethoxyphosphoryl)-3-fluoropropyl phosphate 4, which result from concurrent 1:2 and 2:1 rections, respectively.
