A domino [Pd]-catalysis for the efficient synthesis of fluorenones is presented. The overall reaction proceeds through the formation of a five membered Pd(II)-cycle via a highly regioselective ortho C(sp2)-H activation(s) of simple benzylamine that combines with external iodo arenes to give ortho arylated products. Significantly, the reaction further activates the C(sp3)-H and C(sp2)-H (intramol. oxidative Heck coupling) bonds to give tricyclic imine systems. Then the usual water workup affords the fused tricyclic ketones (fluorenones). Remarkably, this one-pot operation enabled the effective construction of two C-C to three C-C bonds. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Synthetic Route of C8H9IO2).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. Organic iodides are widely used in organic synthesis. Halogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution. Organoiodine lubricants can be used with titanium, stainless steels, and other metals which tend to seize up with conventional lubricants: organoiodine lubricants can be used in turbines and spacecraft, and as a cutting oil in machining.Synthetic Route of C8H9IO2
