The reaction of 2-benzylidene-1,3-diphenylpropanetrione (1a) with phosphorus ylides 2ac afforded the new phosphonium ylides 4a-c. Trialkyl phosphites 3a-c react with 1a to give the respective dialkyl phosphonate products 5a-c. On the other hand, the olefinic compounds 6 and 7 were isolated from the

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 130Β°C nozzle temperature. It has been found that the phenyl rings are nearly coplanar with
