The catalyst-free oxidative cleavage of (Z)-triaryl-substituted alkenes bearing pyridyl motif with ambient air under irradiation of blue LED at room temperature has been developed. The reaction was facile and scalable,...
A catalyst-free oxidative [3+2] cycloaddition of phenols and styrenes was developed with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone as the oxidant and 1,1,1,3,3,3-hexafluoropropan-2-ol as the solvent at room temperature. With this method, a broad range of dihydrobenzofurans were efficiently and quickly obtained from readily available phenols and styrenes.
A novel, simple and eco-friendly strategy for the synthesis of thiopyrano[4,3-b]quinolin-1-ones and pyrrolo[3,4-b]quinolin-1-ones from 2-alkynylquinoline-3-carbonitriles and sodium sulphide (Na2S·9H2O) under catalyst-free conditions at RT.
Oxygenative cleavage of an inert CAr–NH2 bond with concomitant 1,2 amine migration in 8-aminoquinoline derivatives is achieved through an efficient, catalyst free, one step synthesis of 8-benzyloxy, 7-aminoquinoline directly from 8-aminoquinoline in water at room temperature.
Non-isocyanate polyurethanes (NIPUs) were prepared via polyaddition of highly reactive 8-membered ‘bis-cyclic’ carbonates and various diamines under catalyst-free and room temperature conditions.
