Computational study of ethene hydroarylation at [Ir(κ2-OAc)(PMe3)Cp]+

Abstract

Density functional theory calculations have been employed to model ethene hydroarylation using an [Ir(κ2-OAc)(PMe3)Cp]+ catalyst, 1. The reaction proceeds via: (i) an acetate-assisted C–H activation of benzene via an AMLA-6 transition state; (ii) rate-limiting insertion of ethene into the Ir–Ph bond; and (iii) protonolysis of the β-phenylethyl species by HOAc. A range of competing processes are assessed, the most important of which are the C–H activation of ethene at 1 and trapping of the β-phenylethyl intermediate with ethene. The former process gives rise to Irvinyl species which can then access further ethene insertion to give stable allyl by-products. A comparison with other ethene hydroarylation catalysts reported in the literature is presented.
