[small beta]-ketoimidazol(in)ium salts show contrasting reactivity with MHBEt3 due to subtle electronic and steric differences. Thermolysis of the chiral [small beta]-borate imidazolium salts formed from these reactions results in alkane elimination in the first example of organic borates functioning as Bronsted bases.
