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. ...
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 ...
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 ...
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 ...
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 ...
