The combination of palladium salts and bipyridyl ligands can lead to the formation of a large variety of coordination complexes, with different shapes and sizes, displaying a very versatile host-guest chemistry. Increasing their structural complexity remai ...
Selective cleavages of carbon-carbon bonds catalyzed by transition-metal complexes have been shown to be increasingly versatile tools for organic synthesis allowing for complementary synthetic strategies. Numerous examples of transition-metal catalyzed C-C ...
This thesis consists in an extensive study about the enantioselective Pictet-Spengler reaction (EPSR) and its application to the total synthesis of monoterpene indole alkaloids (MIAs). The general introduction presents the literature background about this ...
Carbonate radical (CO3-) is a powerful oxidant that is present in sunlit surface waters and in waters treated by advanced oxidation processes. The production of CO3- in aqueous solution through oxidation of carbonate anion by excited triplet states of arom ...
This paper presents a feasibility study on the development of a gas preconcentrator based on micro-reactor technology on silicon. The objectives are to select a gas adsorbent material, to produce a silicon micro-reactor with an integrated heater, and final ...
The effect of the excitation wavelength on the charge recombination (CR) dynamics of several donor−acceptor complexes (DACs) composed of benzene derivatives as donors and of tetracyanoethylene or pyromellitic dianhydride as acceptors has been investigated ...
cf. CA 55, 13345i. MeOCH2Ph3PCl (I), m. 201-2 Deg (decompn.) (CHCl3-AcOH), was prepd. (86%) from 0.19 mole Ph3P (II) and 0.2 mole ClCH2OMe in 120 ml. C6H6 (60 hrs. at 50 Deg); I borate analog m. 198-9 Deg (Me2CO-EtOH). Ph2CO (0.02 mole) dissolved in 40 ml. ...
