Note générale : Mémoire de Master : Génie Chimique : Royaume-Uni, University of Sheffield : 1983 Bibliogr. f. 121 - 123 Langues : Anglais (eng) Mots-clés : Ketenes Cyclobutanone  ring Spectroscopic  studies t-butylcyanoketene Index. décimale : Ms00583 Résumé : Ketenes have been reacted with a number of polyenes to give the 1 : 1 and 2 : 1 adducts. The influence of the first formed cyclobutanone ring on the regioselectivity and stereoselectivity of the second ketene addition was studied. From the reaction of the 1 : 1 adduct (cyclohexadiene : diphenylketene) with diphenylketene and t-butylcyanoketene, the only isolated products were the 2. The only isolated product from the reaction of the 1 : 14 adduct (cyclopentadiene : diphenylketene) with t-butylcyanoketene, was the 2. The only isolated product from the reaction of cycloheptatriene with diphenylketene, was the 1. The 1 : 1 adduct (butadiene : diphenylketene) failed to react with diphenylketene and t-butylcyanoketene. Cycloaddition reactions of ketens [texte imprimé] / Ahmed Lakoues, Auteur ; G. A.
