A method for the preparation of 3-bora-9aza-indene heterocycles based on zirconocene mediated functionalization
of the ortho-CH bonds of pyridines has been developed and used to make two such compounds. Unlike other methods, the boron
center in these heterocycles remains functionalized with a chloride ligand and so the compounds can be further elaborated through
halide abstraction and reduction. The utility of the method was further demonstrated by applying it towards the preparation of 1,5-
dibora-4a,8a-diaza BN analogues of the intriguing hydrocarbon s-indacene starting from 2,5-dimethylpyrazine. Gram quantities of
one such compound was prepared and fully characterized, and both experimental and computational data is presented to compare its
properties to those of the parent hydrocarbon s-indacene. These data indicate that the BN substituted derivative exhibits lowered
aromaticity in relation to the hydrocarbon.
