Intramolecular olefination of esters having a thioacetal moiety was studied. The treatment of ω,ω-bis(phenylthio)alkyl alkanoates with Cp2Ti[P(OEt)3]2 and the following hydrolysis gave ω-hydroxy ketones in good yields. (C) 2000 Elsevier Science Ltd.
Titanocene(II)-promoted intramolecular olefination of thiol esters: A new route to substituted 2,3-dihydrothiophenes

The treatment of S-[3,3-bis(phenylthio)propyl] thioalkanoates with the low-valent titanium species Cp2Ti[P(OEt)3]2 in THF produced 5-substituted 2,3-dihydrothiophenes in good yields. These thiophene derivatives were found to be susceptible to photoirradiation and easily isomerized into 2-alkylidenetetrahydrothiophenes.

A very general preparative method for homoallyllithiums consists of reductive lithiation of homoallylithiums consists of reductive lithiation of homoallyl phenyl sulfides by lithium 4,4'-di-tert-butylbiphenylide.The sulfides can be prepared by a variety o
Carbenoid Anion Behavior of Dilithio Derivatives of Thioacetal Alcohols. Stereochemistry and Mechanism of Ring Closures by Oxyanion-Facilitated CH Bond Insertion
Ritter, Robert H.,Cohen, Theodore
, p. 3718 - 3725 (2007/10/02)
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
