A novel fluorous DMAP quaternary ammonium iodide salt organocatalyst was prepared. This fluorous organocatalyst was successfully employed to the acylation reaction at room temperature without the use of a stoichiometric amount of external base. It could be recovered 3 times from the reaction mixture by simple precipitation with excellent purity for direct reuse.

The effect of oxidatively stable L- and X-type additives on the activity of Cp?Ir catalyst precursors in the C-H activation of arenes has been studied. Turnover numbers for C-H activation of up to 65 can thus be achieved, as determined by H/D exchange in MeOH-D4. In particular, carbonate additives are found to enhance the C-H activation reactivity of Cp?Ir(H2O)3(OTf)2 (1) more significantly than L-type ligands investigated in this study. Based on these studies, Cp?Ir/carbonate systems are developed that catalyze the aerobic Csp3-H oxygenation of alkyl arenes, employing air as oxidant.
