Mechanistic Studies on the Metal-Free Activation of Dihydrogen by Antiaromatic Pentarylboroles

2013

The perfluoro- and perprotiopentaphenylboroles 1 and 2 react with dihydrogen to effect H–H bond cleavage and formation of boracyclopentene products. The mechanism of this reaction has been studied experimentally through evaluation of the kinetic properties of the slower reaction between 2 and H2. The reaction is first-order in both [borole] and [H2] with activation parameters of ΔH⧧ = 34(8) kJ/mol and ΔS⧧ = −146(25) J mol–1 K–1. A minimal kinetic isotope effect of 1.10(5) was observed, suggesting an asynchronous geometry for H–H cleavage in the rate-limiting transition state. To explain the stereochemistry of the observed products, a ring-opening/ring-closing mechanism is proposed and suppo…
