Triphosphetanones, the First Cyclic Phospha‐Urea Derivatives with Four Ring Structure The reaction of the 1,3‐bis(trimethylsilyl)substituted diphospha‐urea derivative 1 with dichlorophosphanes leads to cyclisation with formation of the four‐membered triphosphetanones 4 . A characteristic feature of the new class of compounds is the CO‐elimination by sun‐light.
