for oxygenation of [Fe2(mu-O2CAr(Tol))2(O2CAr(Tol))2(N,N-(C6H5CDH)2en)2] and [Fe2(mu-O2CAr(Tol))2(O2CAr(Tol))2(N,N-(C6H5CD2)(C6H5CH2)en)2] are 1.3(1) and 2.2(2) at 23 degrees C, respectively. The positive slope rho and low KIE(intra) values are consistent with a mechanism involving one-electron transfer from the dangling nitrogen atom in N,N-Bn2en to a transient electrophilic diiron intermediate, followed
