Abstract
AbstractWe report the facile and efficient synthesis of common electrophilic haloboranes via a protonolysis reaction between Piers’ borane, HB(C6F5)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, (C6F5)2BCl(OEt2) (1) and (C6F5)2BBr(OEt2) (2), as well as the ether‐free tri‐coordinate species, (C6F5)2BBr (3).
