Stable nitrile oxides react with Pt(PPh3)2L (L = PPh3,C2H4) to give 1 : 1 products; X-ray studies show that the nitrile oxide is deoxygenated by triphenyl-phosphine and that a phenyl group migrates to the platinum atom to give the complexes [Pt(Ph)(OPPh2)(RCN)(PPh3)].

A series of “push-pull” molecules, each incorporating a pentafluorophenyl ring as an inductive accepting group, has been synthesised. The NLO properties of these compounds were measured in solution by EFISH (operating at 1907 nm) and in the solid state by the Kurtz powder technique (at 1907 nm). Values of μβ, the product of the molecule dipole moment and its first-order hyperpolarizability, of up to 200 × 10−48 esu were obtained. (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)

The doping of a widely used active polymeric matrix, the polyvinyl carbazole (PVK), with an organic blue emitter has been studied by both continuous wave and time resolved photoluminescence spectroscopy. It is found that the overall emission efficiency of the blend is controlled by two processes: the resonant transfer from the donor to the acceptor and the hopping between the donor sites. Because of the observed spectral variations of the emission spectrum of PVK (donor) with the temperature, both ...

Sodium borohydride-carbonyl reduction of the novel 3-(2-fluoro-5-nitro) phenyl-4-benzoyl-2-azetidinones 3 and 7 gave quantitatively the stereoisomeric carbinols (4R p ,5S p )-4 and (4R p ,5R p )-5. Treatment of the latter with sodium hydride gave the title compounds 8 and 9, respectively, with good overall yield. The rationale of the stereochemical relationships outlined in the sequences 3 (or 7)!4!8 and 3 (or 7)!5!9 is given according to the conformational and keto-enol equilibria of the reactant(s). q 2003 ...

The resonant energy transfer (RET) between fluorescent organic molecules is a very important phenomenon widely investigated for its potential in developing devices such as light-emitting diodes and lasers. Energy transfer processes take place between two different molecules and they are usually observed when the emission spectrum of the first molecule (called donor) overlaps with the absorption spectrum of the other one (called acceptor). The individuation of this kind of molecule inside a common structural ...

A highly enantioselective synthesis of β-lactams "via" a [2+2] cycloaddition reaction of homochiral tricarbonyl [N-(2-methoxybenzylidene)aniline]chromium with ketenes is reported. Moreover the reaction of (+)-(1S)-tricarbonyl[4-methoxy-N-(2-methoxy cinnamylidene)aniline]chromium with acetoxy ketene gives the corresponding 4-styryl-β-lactam in good yield but with moderate stereoselection.

We synthesized a series of polyfluoro-amino-stilbenes in satisfactory yields by Wittig reaction of 4-piperazinyl-benzalhehydes with pentafluoro-benzylidene-triphenyl-phosphorane and we analyzed the photochemical behavior of these stilbenes in the solid state; thanks to arene–perfluoroarene π–π interactions, some of them have shown a good propensity to give the corresponding cyclobutane photodimers in quantitative yields. The photocyclization is reversible both in solution and in polymeric matrix, ...

Silver acetate-promoted nitrilimines cycloaddition onto 3(R*)-phenyl-4(R*)-cinnamoyl-2-azetidinone 1 were highly stereoselective giving 4-(4,5-dihydropyrazol-5-yl) carbonyl-2-azetidinones 5 as the major products and regioisomeric 4-(4,5-dihydropyrazol-4-yl) carbonyl-2-azetidinones 6 as the minor one. When the same protocol was applied to the novel 3(R*)-phenyl-4(S*)-(4-benzoyl-E,E-1,3-butadienyl)-2-azetidinone 2 it resulted in site- and regioselective but not stereoselective cycloaddition, involving ...
