Copper(II)-catalyzed preparation of alkylindium compounds and applications in cross-coupling reactions both in aqueous media
An efficient water-based method for the synthesis of alkylindium compound in the presence of a catalytic amount of cheap and readily available CuSO4·5H2O (10 mol%) was developed. The thus-generated alkylindium compounds effectively underwent palladium-catalyzed cross-coupling reactions with a myriad of aryl halides in aqueous media, leading to the cross-coupled products in modest to high yields. The mildness of the formed alkyl organometallics allowed the tolerance to various important functional groups incorporated in both substrates of alkyl iodides and aryl halides.

Cobalt(II)-catalyzed preparation of alkylindium reagents and applications in cross-coupling with aryl halides
The direct insertion of indium powder into alkyl iodides was found to be efficiently catalyzed by a catalytic amount of cobalt(II) bromide (10 mol%). Upon subjection of the thus-formed alkylindium compounds to palladium-catalyzed cross-coupling reactions with a wide range of aryl halides, a series of cross-coupled products could be obtained in moderate to good yields with the tolerance to many important functional groups.

Preparation of Alkyl Indium Reagents by Iodine-Catalyzed Direct Indium Insertion and Their Applications in Cross-Coupling Reactions
An efficient method for the synthesis of alkyl indium reagent by means of an iodine-catalyzed direct indium insertion into alkyl iodide in THF is reported. The thus-generated alkyl indium reagents effectively underwent Pd-catalyzed cross-coupling reactions with various aryl halides, exhibiting good compatibility to a variety of sensitive functional groups. By replacing THF with DMA and using 0.75 equiv of iodine, less reactive alkyl bromide could be used as substrate for indium insertion with equal ease.

Cesium carbonate-catalyzed indium insertion into alkyl iodides and their synthetic utilities in cross-coupling reactions
A catalytic amount of cesium carbonate (10?mol%) was found to be capable of effectively catalyzing the insertion of indium powder into alkyl iodides. The thus-generated alkyl indium reagents could readily undergo palladium-catalyzed cross-coupling reactions with a wide variety of aryl halides, showing compatibility to a range of important functional groups.

Application of novel coupling reaction to preparing carbon-carbon bond structured compounds
The invention relates to application of a novel coupling reaction to preparing carbon-carbon bond structured compounds and mainly provides a reaction between alkyl indium compounds and halides. The reaction between the alkyl indium compounds and the halides can produce corresponding carbon-carbon structured products. The novel coupling reaction is high in process yield, broad in functional group tolerance and good in compatibility.

Chemically-induced discotic liquid crystals. Structural, studies with NMR spectroscopy
The use of nuclear magnetic resonance (NMR) spectrometry for the structural studies of chemically-induced discotic liquid crystals was discussed. The synthesis of the phase inductor with two deutrons in the phenyl ring was accomplished in a single step using the catalytic exchange procedure. The reaction was quenched by the addition of 5 ml D2O, the organic layer was left to evaporate and 0.38 g of the product was obtained. The degree of deuteriation was found by proton NMR to be approximately 70%.

The Synthesis of 3-Aryl-6-alkylpyridazines
Nine compounds of general structure R-X-Y-R' where X is a para-disubstituted phenyl ring and Y is a 3,6-disubstituted-pyridazine ring were synthesized.These can be used as liquid crystal dopents.A general procedure for their synthesis was developed.N-Alkyl benzene and ethyl butyrylacetate were used as starting materials.The purification of reaction intermediates was not necessary if preparative hplc was used to purify the final products.Very pure materials were obtained with good yield.Their structure was confirmed by carbon 13 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.

Study of the Influence of Molecular Length on the Characteristics of the Ordered Smectic Phase.
Study of DTA and X-rays of p-phenyl-benzylidene-p'-alkylanilines of mesomorphic phases demonstrates the predominant role of the aliphatic chain length. In effect, it governs the appearance of the different phases; the correlation between layers decreases for greater chain lengths. The nonlinear variations of SmB layer thickness for these compounds shows clearly the importance of steric effects coupled with the molecular length with respect to the dipolar effect.
