Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Parenthood</bold>: The reaction of [TpIr(C₂H₄)₂] (<bold>1</bold>) (Tp=hydrotris(pyrazolyl)borate) with acetylene in CH₂Cl₂ affords a 1:1 mixture of the "parent" metallabenzene <bold>2</bold> (that is, all the ring carbon centers are CH units) and the β‐Cl substituted vinyl species <bold>3</bold>. Generation of <bold>2</bold> is by the coupling of an iridacyclopentadiene (formed from two acetylene molecules at the Ir center) with the dichloromethane‐derived chlorocarbene ":C(H)Cl" and a subsequent α‐Cl elimination event.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg37r9m0ck" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
