Synthesis of highly functionalized 9,10-anthraquinones

Molecular conformational analysis, vibrational spectra, NBO, NLO analysis and molecular docking study of bis[(E)-anthranyl-9-acrylic]anhydride based on density functional theory calculations

“…A large value of second order stabilization energy E (2) shows that the interaction is more intense between electron donors and acceptors. The delocalization of electron density between occupied Lewis type NBO orbital and formally unoccupied non-Lewis orbital correspond to a stabilizing donor -acceptor interaction.…”

“…Anthracene derivatives, especially anthraquinones, are significant building blocks in the synthesis of dyes and pigments [1,2], pharmaceuticals [3,4] and agrochemicals [5], including pesticides and insecticides [6] and additives for the paper making industry [7]. Anthracenes are also materials that can be electroluminescent and from this perspective have been attracting interest in different applications as well as in basic science [8].…”

Molecular conformational analysis, vibrational spectra, NBO, NLO, HOMO–LUMO and molecular docking studies of ethyl 3-(E)-(anthracen-9-yl)prop-2-enoate based on density functional theory calculations

“…Anthracenes are important building blocks for the synthesis of dyes and pigments [1,2], pharmaceuticals [3,4], agrochemicals [5], light emitting devices [6], and additives used in the paper making industry [7]. Anthracene itself was the first well-studied electroluminescent material, and along with its derivatives remains of interest for its electro-optical applications [8,9].…”

Preparation of Stabilized Phosphorus Ylides via Multicomponent Reactions and Their Synthetic Applications

“…The reaction of the 1:1 triphenylphosphine-dialkyl acetylenedicarboxylate adducts with some other N-H acids have provided corresponding pyrrole derivatives via an intramolecular Wittig reaction [110][111][112][113][114][115][116][117][118][119].…”
