Aggregative activation and carbanion chemistry: Complex base deprotonation and directed functionalisation of dithioacetals

Bis(phenylthio)methane and [1,3]-dithiane were efficiently deprotonated by the NaNH2-Et(OCH2CH2)2-ONa complex base. A marked behaviour difference was observed between the sodium carbanion of [1,3]-dithiane and the corresponding lithio-derivative. A 'radicaloid' mechanism is proposed to explain the results observed.

Ring-closing metathesis of titanium - Carbene complexes prepared from thioacetals having a carbon - Carbon double bond

The ring-closing metathesis proceeded to give cycloalkenes in good yields when diphenyl thioacetals having a carbon-carbon double bond were treated with the low-valent titanium species Cp2Ti[P(OEt)3]2 in THF at room temperature and then at reflux. This methodology is successfully applied to the preparation of cyclic ethers and sulfides. (C) 2000 Published by Elsevier Science Ltd.
