Modulation De La Regiochimie De La Reaction Du Fluoroborate De 2-Benzoyl-1,2-Dihydroisoquinaldonitrile Sur L'Indene
Autor: Noël Rodier, Marie-France Mercier, F. Theobald, Gérard Schmitt, Karin Monnier
Publikováno v: Bulletin des Sociétés Chimiques Belges. 101:109-112
The reaction of the 2-benzoyl-1,2-dihydroisoquinaldonitrile fluoroborate salt with indene leads to a single indeno[1,2-c]pyrrole derivative. But nmr data did not prove the regiochemistry of the reaction and a chemical demonstration has been carried o

Spiropyrazolines have been synthetized by 1,3-dipolar cycloaddition of some 2-arylidene-1 -tetralones with diarylnitrilimines. It is shown that ring-closure reaction is regiospecific. The diastereoselectivity of the reaction is strongly dependent on

Étude de la stéréochimie de la réaction de cycloaddition dipolaire-1,3 de quelques 5-phényl-3,6-dihydro-2H-1,4-oxazin-2-ones avec les N-méthyl et N-phénylmaléimides

Six derivatives of 5-phenyl-3,4-dihydro-2H-1,4-oxazin-2-ones 1 were synthetized from α-amino acids. These compounds are precursors of six-membered cyclic azomethine ylids involving one stereocenter. The 1,3-dipolar species react with N-methyl and N-

Syntheses and electrochemical behaviour of novel dithiolatoniobium-(IV) and -(V) complexes with two η5-cyclopentadienyl rings
Autor: Kunio Shimizu, Marie-France Mercier, Fabrice Guyon, Jacques Amaudrut
Publikováno v: Journal of Organometallic Chemistry. 465:187-191
Novel niobium(IV) complexes with two cyclopentadienyl rings and dmit, dmio or dddt were synthesized, and their voltammometric behaviour was investigated in acetonitrile and dichloromethane. These complexes in acetonitrile solution exhibited a reversi

NMR kinetic study of ethyl silicate hydrolysis by ammonia in alcoholic solvents
Autor: Idriss El Bakali, Essaïd El Rhess, R. Mercier, Christophe Rousselot, Marie-France Mercier
Publikováno v: Canadian Journal of Chemistry. 70:1612-1617
Hydrolysis of Si(OC2H5)4 by ammonia has been investigated using 1H and 13C NMR measurements in alcoholic media. Use of deuterated CD3CD2OD and CD3OD solvents proves the absence of transesterification by alkoxy exchange between silicate and alcohols.
