Carbenoid Anion Behavior of Dilithio Derivatives of Thioacetal Alcohols. Stereochemistry and Mechanism of Ring Closures by Oxyanion-Facilitated CH Bond Insertion

Article abstract of DOI:10.1021/ja00273a028

Like other lithio derivatives of thioacetals bearing a second anionic site, dilithio derivatives of 3,3-, 5,5-, and 6,6-bis(phenylthio) alcohols decompose at or below ambient temperature to yield products ascribable to carbenoid intermediates.The 5,5-deri
