摘要:
AbstractThe fragmentation of alkenes after chemical ionization with NO+, involving cleavage of the double bond, has been elucidated by deuterium labelling.
Titanocene(II)-Promoted Olefination of ω,ω-Bis(phenylthio)alkyl Alkanoates. A New Method for the Preparation of ω-Hydroxy Ketones
摘要:
Intramolecular olefination of esters having a thioacetal moiety was studied. The treatment of omega,omega-bis(phenylthio)alkyl alkanoates with Cp2Ti[P(OEt)(3)](2) and the following hydrolysis gave omega-hydroxy ketones in good yields. (C) 2000 Elsevier Science Ltd. All rights reserved.
