Synthesis of benzophenones from geminal biaryl ethenes using m-chloroperbenzoic acid
摘要:
The oxidation of geminal biaryl ethenes 3 and 1,3-enynes 5 using m-chloroperbenzoic acid in dichloromethane at room temperature presents a catalyst-free approach for the synthesis of functionalized benzophenones 4 and ynones 6, respectively. (C) 2009 Elsevier Ltd. All rights reserved.

Aryliodides react with metal organotellurolates in tetrahydrofuran/dimethylformamide in the presence of CuI (5 mol %) or CuI (5 mol %) and 1,10-phenanthroline (10 mol %) to afford the corresponding aryl–alkyl tellurides in good yields.
