Noble metal catalysed hydrogenation of carbocations: a key step in the rapid hydrogenation of aromatic hydrocarbons with HF–, HF–TaF₅–, and HF–BF₃–noble metal catalysts

Abstract

Pd–C, Pt–C, and Ir–C catalyse the rapid and complete hydrogenation of carbocations formed through the protonation of aromatic hydrocarbons in super acid media and of stabilised carbocations in aprotic media.
