Abstract

The room-temperature reaction of (η&lt;SUP&gt;5&lt;/SUP&gt;-C&lt;INF&gt;5&lt;/INF&gt;H&lt;INF&gt;5&lt;/INF&gt;)Co(PPh&lt;INF&gt;3&lt;/INF&gt;)&lt;INF&gt;2&lt;/INF&gt; (&lt;BO&gt;5&lt;/BO&gt;) with aliphatic nitro compounds, RNO&lt;INF&gt;2&lt;/INF&gt;, where R = Me, Et, iPr, leads to formation of the corresponding η&lt;SUP&gt;1&lt;/SUP&gt;-nitroso derivatives (η&lt;SUP&gt;5&lt;/SUP&gt;-C&lt;INF&gt;5&lt;/INF&gt;H&lt;INF&gt;5&lt;/INF&gt;)Co(PPh&lt;INF&gt;3&lt;/INF&gt;)[η&lt;SUP&gt;1&lt;/SUP&gt;(N)-N(O)R] (&lt;BO&gt;6&lt;/BO&gt;-Me, R = Me; &lt;BO&gt;6&lt;/BO&gt;-Et, R = Et; &lt;BO&gt;6&lt;/BO&gt;-Pr, R = iPr). Aromatic nitro compounds, ArNO&lt;INF&gt;2&lt;/INF&gt;, where Ar = −C&lt;INF&gt;6&lt;/INF&gt;H&lt;INF&gt;5&lt;/INF&gt;, −p-C&lt;INF&gt;6&lt;/INF&gt;H&lt;INF&gt;4&lt;/INF&gt;C&amp;tbd1;CTMS, undergo reaction with &lt;BO&gt;5&lt;/BO&gt; to give the μ-η&lt;SUP&gt;1&lt;/SUP&gt;:η&lt;SUP&gt;2&lt;/SUP&gt;-nitroso derivatives, [(η&lt;SUP&gt;5&lt;/SUP&gt;-C&lt;INF&gt;5&lt;/INF&gt;H&lt;INF&gt;5&lt;/INF&gt;)Co]&lt;INF&gt;2&lt;/INF&gt;[μ-η&lt;SUP&gt;1&lt;/SUP&gt;(N):η&lt;SUP&gt;2&lt;/SUP&gt;(N,O)-N(O)R]&lt;INF&gt;2&lt;/INF&gt; (&lt;BO&gt;7&lt;/BO&gt;-Ph, R = −C&lt;INF&gt;6&lt;/INF&gt;H&lt;INF&gt;5&lt;/INF&gt;; &lt;BO&gt;7&lt;/BO&gt;-Ar, R = −p-C&lt;INF&gt;6&lt;/INF&gt;H&lt;INF&gt;4&lt;/INF&gt;C&amp;tbd1;CTMS). Complexes &lt;BO&gt;6&lt;/BO&gt;-Me and &lt;BO&gt;7&lt;/BO&gt;-Ar were characterized by X-ray crystallographic analyses.
