Flow Synthesis of Diaryliodonium Triflates
A safe and scalable synthesis of diaryliodonium triflates was achieved using a practical continuous-flow design. A wide array of electron-rich to electron-deficient arenes could readily be transformed to their respective diaryliodonium salts on a gram scale, with residence times varying from 2 to 60 s (44 examples).
متن کاملOne‐Pot C−H Functionalization of Arenes by Diaryliodonium Salts
A transition-metal-free, mild, and highly regioselective synthesis of nitroarenes from arenes has been developed. The products are obtained in a sequential one-pot reaction by nitration of iodine(III) reagents with two carbon ligands, which are formed in situ from iodine(I). This novel concept has been extended to formation of aryl azides, and constitutes an important step towards catalytic rea...
متن کاملHigh-yielding one-pot synthesis of diaryliodonium triflates from arenes and iodine or aryl iodides.
Unsymmetric and symmetric diaryliodonium triflates are synthesized from both electron-deficient and electron-rich substrates in a fast, high yielding, and operationally simple protocol employing arenes and aryl iodides or iodine.
متن کاملFacile One‐Pot Synthesis of Diaryliodonium Salts from Arenes and Aryl Iodides with Oxone
A straightforward synthesis of diaryliodonium salts is achieved by using Oxone as the stoichiometric oxidant. Slow addition is the key to obtaining good yields and purities of the reaction products, which are highly useful reagents in many different areas of organic synthesis.
متن کاملOne-pot synthesis of quinazoline derivatives via [2+2+2] cascade annulation of diaryliodonium salts and two nitriles.
An efficient one-pot approach to multiple substituted quinazolines with diaryliodonium salt , and two nitriles has been presented. The reaction enables great flexibility of the substitution patterns on quinazolines and is applicable to two different nitriles to give a regio-selective product.
