Novel 1-phenyl(1-thiophen-2-yl)-4-(diphenylphosphoryl)butane-1,3-diones were synthesized by the Claisen-type condensation of 1-(diphenylphosphoryl)propan-2-one with ethyl phenyl(thiophene-2-yl)carboxylates. The tautomeric equilibrium of diketone moiety of phosphine oxides was investigated by .sup.1H and .sup.13C{.sup.1H} NMR spectroscopy. Two speci...
