Ethyl 3-trifluoro-2-diazo-propionate as a potentially useful CF3-containing building block: preparation and [Rh(OAc)2]2-catalysed reaction with nitriles
Abstract
A novel CF3-containing building block, ethyl 3-trifluoro-2-diazo-propionate, was easily prepared and reacted readily with nitriles in the presence of rhodium acetate to afford CF3-substituted oxazoles.
