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 supramol. interaction between calixarene cavity and transition-metal catalytic center may play an important role in this catalytic cycle. This complementary method would be used in organic and medical chem. due to the importance of tertiary aliphatic aldehydes. In the experiment, the researchers used many compounds, for example, 4-Iodobenzoic acid(cas: 619-58-9Recommanded Product: 619-58-9)
4-Iodobenzoic acid(cas: 619-58-9) belongs to organic iodides.Recommanded Product: 619-58-9 The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.
