However, upon treatment with either NaOH (suspension) or (Me<sub>4</sub>N)OH (in MeOH), <b>1</b> was converted into a mixture of <b>2</b> and the μ-alkylidyne species [Mo<sub>2</sub>Cp(μ-SMe)<sub>3</sub>{μ-(η<sup>5</sup>-C<sub>5</sub>H<sub>4</sub>)(<i>t</i>-BuN)CN(<i>t</i>-Bu)C}] (<b>3</b>), in which a deprotonated Cp and both isonitrile ligands of <b>1 </b>are now linked by new carbon−carbon and carbon−nitrogen bonds.
