For example, an organic chemist would never refer to a Friedel-Crafts alkylation or a Fischer indole synthesis as functionalizations of the C-H bond. While these reactions do not involve metal catalysts, the reaction outcomes are the same - the arene ring becomes functionalized by the transformation

This kind of TON increase upon NHC-HCl addition was also observed in telomerisation of dienes with alcohols but increased reaction rates were observed with higher imidazolium salt additive concentrations which is not the case here:

We observe the formation of insoluble palladium black after the completion of the Heck and arylation steps. It may be that palladium colloids are responsible for the hydrogenation chemistry observed. This is under study

Successful reaction with aryl chlorides has been achieved in intermolecular reactions with electron rich zinc pyrroles, and intramolecularly in the formation of five-membered rings in moderate to good yield. See:
