Synthesis of Highly Hindered 1,2-Diaryl Diketones and of cis- and trans-1,2-Diacetoxy-1,2-bis(aryl)ethenes
Abstract
Highly hindered 1,2-diaryl diketones can be synthesized in good yields by the reaction of 1-aryllithium with CO in THF solution at atmospheric pressure; preparation of cis- and trans-1,2-diacetoxy-1,2-bis(Mes)ethene can be also afforded by a similar procedure and further quenching with Ac2O.
