Functionalisation of heteroaromatic N-oxides using organic superbase catalyst.
Functionalisation of quinoline N-oxide was investigated using phophazene base as a catalyst; alkynylation and heteroarylation at 2-position were successfully achieved via nucleophilic addition-elimination process.
متن کاملLiving Radical Polymerization via Organic Superbase Catalysis
Organic superbases reacted with alkyl iodides (R–I) to reversibly generate the corresponding alkyl radicals (R). Via this reaction, organic superbases were utilized as new and highly efficient organic catalysts in living radical polymerization. The superbase catalysts included guanidines, aminophosphines and phosphazenes. Low-polydispersity polymers (Mw/Mn = 1.1–1.4) were obtained up to high co...
متن کاملMetal-free deprotonative functionalization of heteroaromatics using organic superbase catalyst.
Metal-free deprotonative functionalization of heteroaromatic compounds was achieved using an organic superbase catalyst; an organosilicon additive such as trimethylsilylpropyne was employed for activating the catalytic cycle of 1,2-addition to carbonyl compounds.
متن کاملOrganic synthesis using photoredox catalysis
Natural photosynthesis is a remarkable chemical machinery that enables our life on earth and delivers a constant stream of oxygen and organic biomass. We should acknowledge this fact with humbleness, especially because we have not been able yet to mimic this process in a reliable way even after decades of intense research. The basic mechanistic principle behind photosynthesis is photoredox cata...
متن کاملOrganic Synthesis using Clay Catalysts
One of the major current challenges before chemists is to develop synthetic methods that are less polluting, i.e., to design clean or ‘green’ chemical transformations. The chemical manufacturing processes should be such that they do not cause permanent damage to the environment or disturb the ecological balance. Ways to minimize the consumption of energy and raw materials used in synthesis must...
