  A calix[4]arene ligand assisted direct β-C−H arylation of tertiary aliphatic aldehydes has been developed via a Pd-catalyzed C(sp3)−H functionalization process. This strategy exhibited good functional group compatibility and C−H bond site-selectivity. Mechanism studies have shown that both synergistic effect and cationic-π supramolecular interaction between calixarene cavity and transition-metal catalytic
