Abstract

The reactions of 3, 4-dichlorophenylmagnesium bromide and 3, 5- dichlorophenylmagnesium bromide with B (OEt) 3 and NaBF4 were studied The corresponding tetraarylborates [(3, 4-Cl2C6H3) 4B] NH4 and [(3, 5-Cl2C6H3) 4B] Na were obtained and characterized. The significant influence of the substituents inductive effect on the reaction course was revealed. NaBF4 was found to be a valuable boron reagent in the ...
