Transition-Metal-Substituted Diphosphenes, XXVIII. - Synthesis and Structures of the First 1,2-Diaza-3,4-diphosphetidines and (2E,8E)-1,7-Dioxa-3,4,9,10-tetraaza-5,6,11,12-tetraphospha-2,8-cyclododecadienes(η5-C5Me5)(CO)2Fe—P = P—Mes*(Mes* = 2,4,6-tBu3C6H2) reacts with one equivalent of the Δ1-1,2,4-triazoline-3,5-diones (2a: R = Ph; 2b: R = 4-EtOC6H4) in benzene to give the first 1,2-diaza-3,4-diphosphetidines 3a, b. When the same reaction is performed in diethylether the novel (2E,8E)-1,7-dioxa-3,4,9,10-tetraaza-5,6,11,12-tetraphospha-2,8-cyclododecadienes 4a, b are isolated as the sole products. The molecular structures of 3a and 4b are established by single-crystal X-ray analysis.
