The ..gamma.. secondary deuterium isotope effects in the pyrolysis of 1,2-diaza-1-cyclobutene has been determined. Values of the rate constants for the reaction in five experiments are tabulated. The results indicated that the decomposition proceeded by a mechanism involving an unsymmetrical transition state with elementary kinetic effects for the first D exchange unequal to the second D exchange for

normally stable diiron complexes Fe2(CO)6(dtn) (VIc) and Fe2(CO)7(dtn) (VIIc). Ru3(CO)12 and dtn react to form only Ru3CO)9(dtn) (VIIId). Variable temperature13CNMRstudies reveal CO scramblingin VIIIc and VIIId at room temperature, which ceases at low temperature. Results for the dtn complexes are compared with results for another 4-membered ring diazene ligand as well as with results for 3−, 5−
