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
