Le rôle du capital humain dans l’établissement de collaborations internationales des PME1

Autor: Chantal Garcia, Josée St-Pierre, Danièle Benezech, Lucile Defays

Publikováno v: Management international. 18:72-84

Les collaborations internationales sont de plus en plus reconnues pour favoriser l’intégration des PME à l’économie mondiale. Celles-ci leur permettent de combler leur manque de ressources internes mais aussi de s’approprier des connaissance

Dans quelle mesure l'orientation entrepreneuriale se traduit-elle en activités d'innovation dans les PME ?

Autor: Chantal Garcia, Thierry Karcher, Danièle Benezech

Publikováno v: Revue de l’Entrepreneuriat. 12:35-58

A number of studies have examined the link between the construct of entrepreneurial orientation (EO) and organizational performance. This paper examines EO specifically in the context of SMEs by exploring the relationships among EO and innovation act

Kinetic and thermodynamic consequences of the substitution of SMe for OMe substituents of cryptophane hosts on the binding of neutral and cationic guests

Autor: André Collet, Delphine Humilière, Jean-Pierre Dutasta, Chantal Garcia, Nathalie Riva

Publikováno v: Org. Biomol. Chem.. 1:2207-2216

To investigate the origin of the high selectivity of cryptophane-E (1) towards Me3NH+, Me4N+, and CHCl3, and particularly to discriminate the different contributions that stabilize the supramolecular complexes, we have synthesized the new cryptophane

Chiralization in mesogenic 1,3-diacylaminobenzenes

Autor: Jacques Malthête, Chantal Garcia

Publikováno v: Liquid Crystals. 29:1133-1139

The effect of molecular chirality in thermotropic mesomorphic H-bonded polymeric systems has not really been investigated so far. Therefore, five new chiral mesogenic diamides have been prepared and described. Besides more ordered mesophases, the ena

Publikováno v: Langmuir
Langmuir, American Chemical Society, 1996, 12 (22), pp.5407-5412. ⟨10.1021/la960245i⟩

The cryptophanes are spherical or ovoid-shaped hollow molecules of nanometric scale capable of forming inclusion complexes with neutral or charged organic species. Certain cryptophanes such as 1−4 ...

New key compounds in cyclotriveratrylene chemistry. Synthesis, optical resolution, absolute configuration and circular dichroism of C3-cyclotriveratrylenes with sulfur substituents

Autor: Chantal Andraud, André Collet, Chantal Garcia

Publikováno v: Supramolecular Chemistry. 1:31-45

Vanillin 6a and isovanillin 6b were converted via a Newman-Kwart rearrangement to thiovanillin 9a and isothiovanillin 9b, which on S-methylation and subsequent reduction of the aldehyde function gave 3-methoxy-4-methylthio- (3a) and 4-methoxy-3-methy

New optical resolution method based on the formation of a solid solution. Optical resolution of racemic 1-(4-methylthiophenyl)-2-phenylpropan-1-one by co-crystallization with (+)-1-(4-methoxyphenyl)-2-phenylpropan-1-one

Autor: André Collet, Chantal Garcia

Publikováno v: Tetrahedron: Asymmetry. 3:361-364

Crystallization of ketone S-(+)-1 in the presence of a small amount of it sulfur analogue (±)-2 afforded a solid solution containing 8% of S-(+)-2; the latter was isolated in enantiomerically pure form by column chromatography. This simple optical r
