Stereoselective synthesis of vinylic chalcogenides through vinylic substitution by lithium organylchalcogenolates
Silveira,Guerra,Comasseto
, p. 5121 - 5124 (2008/02/09)
Enol phosphates and enol tosilates of β-dicarbonyl compounds react with lithium organoselenolates to give β-organoseleno (Z)-α,β-unsaturated carbonyl compounds. Tetrasubstituted vinylic vic-bis(organylchalcogenides) of (E)-geometry have been prepared by t
Carbonyl transposition on organoselenium compounds
Comasseto, Joao V.,Lo, Wai L.,Petragnani, Nicola
, p. 7445 - 7460 (2007/10/03)
Carbonyl conjugated vinylic selenides undergo 1,3 and 1,5-carbonyl transposition sequences through organometallic reagents addition reactions followed by acid hydrolysis.
A convenient procedure for the preparation of organic selenides
Sakakibara,Katsumata,Watanabe,Toru,Ueno
, p. 377 - 379 (2007/10/02)
Treatment of diphenyl diselenide with tributylphosphine in an alkaline medium forms phenylselenolate ion which converts alkyl halides, α,β-unsaturated ketones, and epoxides into alkyl selenides, (phenylseleno)alkenones, and β-(phenylseleno)alkanols, respe
Reactions of 3-Hydroxyvinyl Selenones with Alkoxides. Oxetane Formation and Fragmentation Reactions
Shimizu, Makoto,Ando, Ryoichi,Kuwajima, Isao
, p. 1230 - 1238 (2007/10/02)
3-Hydroxyvinyl phenyl selenones are prepared and their behavior as conjugate addition acceptors has been investigated.As a result, a selenonyl group has been found to activate the C=C bond for conjugate addition of nucleophiles and further to behave as an
