✦ Synopsis

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 analysis and spectral studies.

'Dedicated to Prof. Hans Jiirgen Bestmann on the occasion "To whom correspcindence should be addressed.
