Abstract: Aseries of 1,3,2-benzodihetero (S,O) borole 2-β-diketonates have been synthesized by reacting 2-chloro-5-methy-1,3,2-benzodithioborole or 2-chloro-1,3,2-benzodioxaborole with β-diketones (acetylacetone, acetoacetylferrocene, benzoylacetone, and dibenzoylmethane). Five of them are reported for the first time. All these compounds are colourful solids and the stability of benzodithio-borole derivatives is less than that of benzodioxaborole derivatives. The IRand 1H NMR data indicate that they have similar chelate structure and the framework π electrons of β-diketones are extensively delocalized in these molecules.
