- Ultrafast relaxation processes of triarylpyrylium cations
-
The time evolution of the fluorescence and the photoinduced absorption spectra of four triarylpyrylium cations, differing in the number of dodecyl chains attached to the chromophore, was studied by means of femtosecond fluorescence upconversion and picose

- Polyethylene as a nonvolatile solid cosolvent phase for catalyst separation and recovery
-
The studies described here show that a relatively low molecular weight, narrow polydispersity polyethylene (PE) wax (Polywax) can serve as a nontoxic and nonvolatile alternative to alkane solvents in monophasic catalytic organic reactions where catalysts

- Synthesis, insecticidal evaluation of novel 1,3,4-thiadiazole chrysanthemamide derivatives formed by an EDCI/HOBt condensation
-
A series of novel pesticides with two components derived from a 1,3,4-thiadiazole and chrysanthemic acid were synthesised via an EDCI/HOBt condensation. These 1,3,4-thiadiazole chrysanthemamides were identified by IR, 1H NMR and elemental analyses. Their insecticidal activity was also evaluated.

- One-step synthesis of novel flavylium salts containing alkyl side chains in their 3-, 4′-, 5- or 6-positions and their photophysical properties in micellar media
-
A one-step preparation of several flavylium salts containing alkyl side chains in their 3-, 4′-, 5- or 6-positions is described. Flavylium salts with alkyl side chains in positions 3 or 4′ were isolated from reactions between 2,4-dihydroxybenzaldehyde and

- Nouveaux diamino-3,4 phenylalcanes et leur transformation en benzimidazolemethanethiols-2
-
We report five o-phenylenediamines which are substituted by an aliphatic chain containing n carbon atoms (n = 4, 6, 8, 10, 12).We describe a well adapted general synthetic method using Schmidt's reaction.The diamines were then transformed into 2-benzimidazolemethanethiols and their related S-methyl derivatives which structures were checked by (1)H NMR.

- Multiple Melting Behaviour in Square-planar trans-Bis-(1-p-n-alkylphenylbutane-1,3-dionato)copper(II) - The Effect of Alkyl Chain Length
-
The title complexes having different n-alkyl groups from methyl to dodecyl have synthesized.All these complexes exhibit solid polymorphism.The number of polymorphs depends on the length of the alkyl chain: two for n (the number of carbon atoms) = 0-2, three for n = 3-5 and 12, and four for n = 6-11, respectively.Each polymorphic form except those with the highest m.p.s. exhibits multiple melting behaviour: double melting for n = 0-5,8, and 12, and triple melting for n = 6-11 except 8.The m.p.s. of the complexes with alkyl groups of odd carbon atoms are higher than those with even atoms, while the respective ligand solids show the opposit e even-odd effect in their m.p.s.

A process for the manufacture of alkylacetophenones wherein (1) benzene is acylated, (2) the alkylaryl ketone thus obtained is hydrogenated catalytically, and (3) the alkylbenzene thus obtained is acetylated, in only one solvent chosen from among chlorinated aliphatic hydrocarbons containing 1 to 3 carbon atoms and 2 or 3 chlorine atoms per molecule, and their mixtures.
