PROXIMITY EFFECT IN ARENE Pi-COMPLEX FORMATION
A proximity effect in arene ^-complex formation from the reaction system of an aryl G r i g n a r d reagent and anhydrous chromic chloride was investigated. The yields of arene ^-complexes and any accompanying reaction products were compared by the systematic variation of the aryl G r i g n a r d reagent employed. Phenyl G r i g n a r d gave the best yield of jr-complex followed by the benzyl, ...
متن کاملInvestigate formation constant of some Amino Acids by p-sulphonato-calix (4) arene in Aqueous Solution
The formation constants (log K), of the complexes formed between a number of amino acids(glycine , L-valine and L-alanine) with p-sulfonatocalix [4] arene at varying temperatures (25± 0.1to 65 ± 0.1 °C) in aqueous solutions and at natural pH of p-sulphonato-calix [4] arene (pH=3.2) bymeans of UV-Vis spectrophotometeric technique have been investigated. At this pH the guestmolecule is in its cat...
متن کاملDirect Formation of Tethered Ru(II) Catalysts Using Arene Exchange
An 'arene exchange' approach has been successfully applied for the first time to the synthesis of Ru(II)-based 'tethered' reduction catalysts directly from their ligands in one step. This provides an alternative method for the formation of known complexes, and a route to a series of novel complexes. The novel complexes are highly active in both asymmetric transfer and pressure hydrogenation of ...
متن کاملStereoselective C,C-bond formation. Cyclizations of biradicals*
However, for reactions between two radicals, which occur with diffusion-controlled rates, one cannot expect that substituents induce stereoselectivity. We have now shown that this changes in reactions of photolytically generated biradicals: Both the singlet and the triplet biradicals can react with high stereoselectivity, but the outcome of the reactions depends upon the multiplicity of the bir...
متن کاملStrain-induced stereoselective formation of blue-emitting cyclostilbenes.
We describe the synthesis of two conjugated macrocycles that are formed from the end-to-end linking of stilbenes. We have named these macrocycles cyclostilbenes. The two cyclostilbene isomers created in this study differ in the configuration of the double bond in their subunits. These macrocycles are formed selectively through a stepwise reductive elimination from a tetraplatinum precursor and ...
