The chemical preparation of M[O(R)PhCH(CH{double_bond}N(tBu))N(tBu)]{sub 2} (M = Zr, R = Me (4a), R = Ph (4b) and M = Hf, R = Me (5a), R = Ph (5b)) complexes is described. The reaction can be described as a 1,3-dipolar cycloaddition of C{double_bond}O across the M-N-C portion of Zr and Hf 1,4-diaza-1,3-diene complexes. The crystal structures of 4a and 5b are reported.
