Reactions of 2-Aminoazulenes with Electron-Deficient Acetylenes

Diversity-Oriented Synthesis Based on the DPPP-Catalyzed Mixed Double-Michael Reactions of Electron-Deficient Acetylenes and β-Amino Alcohols

In this study, we prepared oxizolidines through 1,3-bis(diphenylphosphino)-propane (DPPP)-catalyzed mixed double-Michael reactions of β-amino alcohols with electron-deficient acetylenes. These reactions are very suitable for the diversity-oriented parallel syntheses of oxizolidines because: (i) they are performed under mild metal-free conditions and (ii) the products are isolated without compli...

Solvent-Free Multicomponent Reactions of Dithiocarbamates, Activated Acetylenes and Isocyanides

An efficient method to synthesis the 2H-pyrans using three component reactions of dithiocarbamats, activated acetylenes and isocyanides in water as the solvent is described. In these reactions, synthesis of 2H-pyrans is possible based on the one-pot reaction and without using any catalyst. The mild reaction conditions and high yields of the products exhibit synthetic advantage of these methods.

Reactions of Carbanions with Michael Acceptors and Electron-deficient Arenes: Quantifying Polar Organic Reactivity

solvent-free multicomponent reactions of dithiocarbamates, activated acetylenes and isocyanides

Selective removal of acetylenes from olefin mixtures through specific physicochemical interactions of ionic liquids with acetylenes.

Imidazolium-based ionic liquids (ILs) bearing an alkylphosphite anion, were highly efficient for the selective removal of acetylenes in olefins. Comparison of solubility data at 313 K and at atmospheric pressure shows that the solubilities of acetylene and propyne in 1,3-dimethylimidazolium methylphosphite ([DMIM][MeHPO(3)]) are about 45 and 20 times higher than those of ethylene and propylene,...
