## Abstract Irradiation of vicinal diaryl tetraketones in a variety of solvents yields tricyclic products **2** in high yields. The structure of the product from diβ__p__βbromophenyl tetraketone was determined by Xβray crystallographic analysis.
1,2,3-lndantrione (l), diphenylpropanetrione (6), and alloxan (8) can be converted by reactions with ketenylidene-(2a) and thioketenylidenetriphenylphosphorane (2b) into phosphoranylidenecyclobutanes (5, 7, and 9). The stmctures of the new cyclic compounds were confirmed on the basis of elemental an
## Abstract The behavior of linear and cyclic fluorinated 1,3,5βtriketones and their metal derivatives towards common halogenating agents was examined, and optimal reaction conditions for the straightforward synthesis of monoβ, diβ, and tetrahalogenated products were found (__Schemesβ 1β3__). An aro
