- Cleavage (deprotection) of selenoacetals to carbonyl compoundes: a comparative studyPublication . Burton, A.; Hevesi, L.; Dumont, W.; Cravador, A.; Krief, A.Phenyl and methyls (1) have found increasing interest in organic synthesis. They have been prepared from aldehydes or ketones (2) and selenols, from 1,1-bis(phenylseleno)-alkanes, and from 1,1,1-tris(seleno)-alkanes (5).
- Reduction vs acetalisation of some carbonyl-compounds by means of methylselenol and lewis-acidsPublication . Cravador, A.; Krief, A.; Hevesi, L.Aliphatic ketones and aromatic carbonyl compounds on reaction with methylselenol :and a Lewis acid, are shown to undergo acetalisation and/or reduction to methyl selenide, the unexpected reduction reaction being predominant in most cases.
- Synthesis of selenoacetalsPublication . Clarembeau, M.; Cravador, A.; Dumont, W.; Hevesi, L.; Krief, A.; Lucchetti, J.; Vanende, D.This paper reports our results concerning the syntheses of various bis(alkylseleno)alkanes and some of their arylseleno analogues by different methods. The scope and limitation of each of them are presented.
