Catalytic, oxidant-free, direct olefination of alcohols using Wittig reagents

Reported here is the catalytic, acceptorless coupling of alcohols with in situ generated, non-stabilized phosphonium ylides to form olefins as major products. The reaction uses low catalyst loadings and does not require added oxidants. Hydrogenation of the product is minimized and the reaction leads to Z (aliphatic) or E (benzylic) stereospecificity.

Synthesis and optoelectronic properties of some new thiahelicenes

(Chemical Equation Presented) New symmetrical helically chiral penta- and heptacyclic aromatic systems containing two thiophene rings have been prepared, in good yields, under mild conditions using a photochemical route. Optoelectronic properties of these helically aromatic thia-systems were determined and exhibit interesting behavior. Copyright Taylor & Francis Group, LLC.

Thermal and ionic-conductive behaviors of main chain type liquid crystalline polymers with lithium salt

Two types of the main chain type liquid crystalline polymer were synthesized and measured ionic conductivity. One of the polymers exhibited a smectic phase. The mixture with lithium salt at the ratio of 0.04 per repeating unit also exhibited a smectic phase. However, the mixture with lithium salt (0.11) showed a nematic phase. Ionic conductivity of the mixture with lithium salt (0.11) was larger than that of the mixture with lithium salt (0.04). The trans type polymer exhibited a liquid crystalline phase, while the cis type polymer didn't show. We found that the ionic conductivity of the trans type polymer with lithium salt mixture (0.11) was larger than that of the cis type polymer with lithium salt mixture (0.11) Moreover, the ionic conductivity of the ceramic-polymer with lithium salt composite was larger than that of the ceramic-free polymer with lithium salt. The other polymer showed a nematic phase. The mixture with lithium salt (0.04) or (0.11) also exhibited a nematic phase. Ionic conductivity of the polymer with lithium salt mixture (0.11) was smaller than that of the polymer with lithium salt mixture (0.04).

Flash vacuum pyrolysis of stabilised phosphorus ylides. Part 16. Model studies for the construction of conjugated polymers

Reaction of a range of bis(ylides) with acid chlorides has been used to prepare the bis(oxoylides) 11-15. Similarly a range of simple ylides react with bis(acid chlorides) to give bis(oxoylides) 19-27 with the isomeric structure. Flash vacuum pyrolysis (FVP) of one example of the first type results in extrusion of Ph3P rather than the expected Ph3PO while six examples of the second type do extrude Ph3PO upon FVP at 500 °C to afford the bis(alkynes) 28. Examples of the corresponding bis(tributylphosphonium ylides) have also been prepared but attempts to construct a tetrakis(oxoylide) 31 using a stepwise approach were unsuccessful. Fully assigned 13C NMR spectra are presented for six of the bis(oxoylides).

Process for the manufacture of 1,4-bis[2-(4'-carbomethoxystyrenyl)] benzene

A process for the manufacture of 1,4-bis[2-(4'-carbomethoxystyrenyl)] benzene is disclosed. This process comprises reacting, at a temperature of about 0° C. to about 100° C., in a highly polar anhydrous organic solvent or solvent mixture, or in liquid ammonia, a p-xylylene-bis-(trialkylphosphonium halide) or p-xylylene-bis-(triarylphosphonium halide) with 4-carbomethoxybenzaldehyde, initiated by the slow introduction of an organometallic compound or an inorganic base. Polyesters, such as polyethylene terephthalate, are copolymerized with about 5 to about 20 parts per million of 1,4-bis[2-(4'-carbomethoxystyrenyl)] benzene. 1,4-bis[2-(4'-carbomethoxystyrenyl)] benzene is useful to provide permanent whiteness to polyesters and polyamides and other synthetic or natural polymers. Polyesters are useful for the manufacture of fibers, films, and related industrial products.

Wittig Reactions of Phosphoniomethylaryl Compounds with Sulfonated Aromatic and Heteroaromatic Aldehydes

Bis(triphenylphosphoniomethyl)aryl dichloride derivatives react with aromatic or heteroaromatic aldehydes which have a sulfonic or carboxylic group attached to the ring system, to yield stilbene compounds of a betaine-type structure.These betaines are reacted further with various aromatic or heteroaromatic aldehydes yielding asymmetrically substituted derivatives in excellent yields.This new method is widely applicable to the preparation of water-soluble, fluorescent whitening agents of the bis-stilbene type.
