Reaction of [(h5-C5Me5)Fe(CO)2P:PC6H2(CMe3)3-2,4,6 with 1,2,4-triazoline-3,5-diones I (R = Ph, 4-EtOC6H4) in C6H6 at ambient temp. affords the 1st 1,2-diaza-3,4-diphosphetidines as part of the bicyclic compds. II, whereas in Et2O, the 12-membered macrocycle III is obtained. The structures of II and III were detd. by single-crystal x-ray diffraction.
