between an amine (A) and an alcoxydifluoroboron (B(OR)F2). At low temperature, we characterized the additive compound A → B(OF)F2 which remains stable up to −30°C. By increasing the temperature of this reaction mixture, or through the reaction, at room temperature, between the amine and the alcoxydifluoroboron, we obtained the corresponding borate B(OR)3, and the additive compound A → BF3.

The kinetics of the alkaline hydrolysis of BF3OR− anions (R=C2H5, C3H7) have been investigated. It has been shown that the reaction mechanism includes the solvolytic dissociation of a B-F bond and that the processes resulting in the replacement of the first fluoride ion act as the rate-limiting step. The influence of the electron-donor ability of the substituents on the rate of processes has been studied
