《Synthesis, electronic structure and NH-tautomerism of novel mono- and dibenzoannelated phthalocyanines》 was published in Dyes and Pigments in 2020. These research results belong to Yagodin, Alexey V.; Martynov, Alexander G.; Gorbunova, Yulia G.; Tsivadze, Aslan Yu. Application of 51364-51-3 The article mentions the following:
Novel low-symmetry benzoannelated metal-free phthalocyanines of A3B-, ABAB- and AABB-types were synthesized by statistical condensation of phthalonitrile bearing bulky solubilizing groups (fragment A) and new naphthalonitrile with OH-terminated diethylene glycol anchors (fragment B). Comprehensive phys.-chem. characterization of the synthesized macrocycles allowed to reveal the electronic effects associated with the extension of π-system. The interpretation of the observed effects was performed by theor. calculations where simplified TD-DFT approach at CAM-B3LYP/6-31G(d) level was successfully used for the first time to predict excitation energies of Q-band region in UV-visible spectra of low-symmetry phthalocyanines with errors not exceeding 0.03 eV. Altogether it allowed to identify the spectroscopic signatures of various tautomers including energy-unfavorable forms. In addition to this study using Tris(dibenzylideneacetone)dipalladium(0), there are many other studies that have used Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Application of 51364-51-3) was used in this study.
Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3) is the most widely used PdO precursor complex in synthesis and catalysis, in particular as a catalyst for various coupling reactions. Application of 51364-51-3 It also used for palladium-catalyzed one-pot synthesis of tricyclic indolines, in the Suzuki-Miyaura coupling of 2-pyridyl nucleophiles and cross-coupling of aryl halides with aryl boronic acids.
