Stereoselective domino assembling of five molecules: one-pot approach to $(2^\primeR^*,3S^*,4^\primeR^*)$-$2^\prime,4^\prime$-diaryl-$1^\prime,4^\prime$-dihydro-$2^\primeH $-spiro[indoline-$3,3^\prime$-pyridines]

Comptes Rendus. Chimie, 2020
A new stereoselective multicomponent reaction has been found: domino assembling of two equivalents of benzaldehyde, malononitrile, oxindole and excess of ammonium acetate in acetonitrile resulted in the formation of previously unknown $(2^\primeR^*,3S ...

A new lattice Boltzmann model for interface reactions between immiscible fluids [PDF]

, 2015
In this paper, we describe a lattice Boltzmann model to simulate chemical reactions taking place at the interface between two immiscible fluids. The phase-field approach is used to identify the interface and its orientation, the concentration of reactant
