    • A reviewer has pointed out that the reduced Zr-N p bonding proposed for complex 1 may not be common to intermediates 4 and 5. An alternate electronic rationale for the observed reactivity, such as a formal [2 + 2] cycloaddition between the alkyne and the p contribution to the Zr-N bond, cannot therefore be ruled out. Computational work is currently underway to address these questions
