Reaction of the bis-isonitrile complex [Mo<sub>2</sub>Cp<sub>2</sub>(μ-SMe)<sub>3</sub>(<i>t</i>-BuNC)<sub>2</sub>](BF<sub>4</sub>) (<b>1</b>) with <i>n</i>-BuLi (in hexane)
produced the dealkylated derivative [Mo<sub>2</sub>Cp<sub>2</sub>(μ-SMe)<sub>3</sub>(<i>t</i>-BuNC)(CN)] (<b>2</b>) in quantitative yield. 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.
