A recent report has indicated that the oxidizing agent Oxone does not possess the ability to cleave the 2,3-carbon-carbon bond of indole. Work in our laboratory shows that this is not the case. Indole and a variety of aryl ring substituted derivatives readily react to form synthetically important isatoic anhydrides.

The esterification reaction of phthalic anhydride with methanol was performed at different temperatures in a continuous flow glass microreactor at pressures up to 110 bar and using supercritical CO(2) as a co-solvent. The design is such that supercritical CO(2) can be generated inside the microreactor. Substantial rate enhancements were obtained, viz. a 53-fold increase was obtained at 110 bar ...

This communication deals principally with the development of a method for the quantitative fluorometric measurement of the natural estrogens and introduces data on a similar test method for the quantitative determination of cholesterol. To achieve this goal, use has been made of the condensat.ion reaction of phenolic steroids with phthalic anhydride (1, 2). In view of the wide-spread interest i...

An effective method for the synthesis of photochromic diarylethenes based on microflow systems has been developed, and the synthesis of unsymmetrical diarylethenes which is difficult to achieve using conventional macro batch systems, has been accomplished.

This manuscript describes facile ring-opening/cross-metathesis (ROCM) reactions between unsymmetrical norbornene derivatives and electron-rich olefins in the presence of the second-generation Grubbs' catalyst to generate highly substituted furans and pyrroles.

A series of unsymmetrical distyryl BODIPYs have been prepared which function as highly potent photosensitisers with in vitro IC(50) values as low as 15 nM. Their cellular uptake, subcellular localisation and photocytotoxicity depend greatly on the styryl substituents.

A new method for the synthesis of unsymmetrical calix[4]arenes is described which involves the reaction of a diyne with a bis-carbene complex of chromium. This synthesis of calixarenes is unique in that it involves the formation of two of the four benzene rings of the calixarene and the macrocyclic ring of the calixarene in the same step. Thus, two of the four benzene rings of the calixarene ar...

We report the interfacial properties of a new fluorocarbon-hydrocarbon hybrid surfactant [OH(CH2)11N(C2H4)2(CH2)2(CF2)5CF3 I, or FHUB], which has a fluorocarbon chain as well as a w-hydroxyalkyl chain. This new hybrid surfactant has properties that are different than classical hydrocarbonand fluorocarboncontaining surfactants. This difference is created by combining a fluorocarbon chain and the...

An intermolecular nickel-catalyzed addition reaction has been developed where phthalic anhydrides react with alkynes to afford substituted isocoumarins. A mechanistic rationale is proposed, implying reductive elimination of Ni(0) promoted by ZnCl(2) cocatalyst as the key step of the catalytic cycle.
