Electron diffraction / Gas-crystal structure comparison / Conformation The molecular structure of 1,3-diphenylpropane-1,2,3-trione (diphenyl triketone) has been determined by gas-phase electron diffraction at 130°C nozzle temperature. It has been found that the phenyl rings are nearly coplanar with
distillation under high vacuum at room temperature (time required ca. 48 h). Double recrystallization of the residue from pentane afforded (2) in 50 to 55% yield (based on ( I ) ) . For conversion of (2) into (3) a solution of (2) (2.3 mmol) and Fe(CO), (3 ml) in ether (50 ml) was irradiated at -40
