Expedient Synthesis of 1,2-Thiaborines by Means of Sulfur Insertion into Boroles.


The propensity of boroles to undergo ring expansion reactions has been exploited as a route to generate 1,2-thiaborines, molecules that can be viewed as hybrid inorganic/organic analogues of benzene. Computational studies as well as structural data indicate that the species reported here have a high degree of aromatic character.
