Mg. Banwell et Jh. Knight, THE REACTION OF TETRACHLOROCYCLOPROPENE WITH TRIMETHYLSILOXYBUTA-1,3-DIENES - A ONE-POT DIELS-ALDER ROUTE TO TRICHLOROTROPONES AND TRICHLOROTROPOLONES, Australian Journal of Chemistry, 46(12), 1993, pp. 1861-1868
One-pot syntheses of the trichlorinated troponoid compounds (8), (10),
(12) and (18) have been achieved by reacting tetrachlorocyclopropene
(5) with various trimethylsiloxybuta-1,3-dienes.
