Abstract

Abstract: We report the facile and efficient synthesis of common electrophilic haloboranes via a protonolysis reaction between Piers' borane, HB(C6 F5 )2, and H−X (X=Cl, Br). This route benefits from fast reaction times, easy setup, and minimal workup to yield the analytically pure etherates, (C6 F5 )2 BCl(OEt2 ) (1 ) and (C6 F5 )2 BBr(OEt2 ) (2 ), as well as the ether‐free tri‐coordinate species, (C6 F5 )2 BBr (3 ).
