The title Schiff base compound, C(20)H(14)ClNO(2), adopts an E configuration about the azomethine bond. The phenol and chloro-benzene rings form dihedral angles of 84.71 (9) and 80.70 (8)°, respectively, with the phenyl ring and are twisted by 15.32 (8)° with respect to one another. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond, which forms an S(6) ring mot...
The title chiral photochromic Schiff base compound, C(16)H(17)NO(2), was synthesized from (R)-1-phenyl-ethyl-amine and 5-methoxy-salicylaldehyde. The mol-ecule of the title compound exists in the phenol-imine tautomeric form. The dihedral angle between the two aromatic rings is 62.61 (11)°. An intra-molecular O-H⋯N hydrogen bond with an O⋯N distance of 2.589 (2) Å is observed. The crystal packi...
Title compound was designed to be a black quencher of pyrene fluorescence. It was made amphiphilic to serve as a membrane-bound probe. The synthesis is a two-step procedure. The first step is a Mitsunobu reaction of [{(phenyldiazenyl)phenyl}diazenyl]phenol with 1,2-O-isopropylideneglycerol. The second step is the cleavage of the isopropylidene protecting group. The title compound has the extinc...
We report a sono-Fenton strategy to mediate the supramolecular assembly of metal–phenolic networks (MPNs) as substrate-independent coatings using phenol and phenyl derivatives building blocks. The process is initiated from generation hydroxyl radicals (.OH) high-frequency ultrasound (412 kHz), while metal ions synergistically participate in production additional .OH for hydroxylation/phenolatio...
Conventional process of nitrating phenolic compounds involves the use excess corrosive reagents that impose environmental threats. Rapid and environmentally friendly microwave-assisted nitration phenol has been employed to limit nitric acid sulfuric acid. In this study, is reacted calcium nitrate acetic acid, which served as agents. The solution irradiated under microwave complete process. This...
The reaction of the phenyl radical (C6H5) with molecular oxygen (O2) plays a central role in the degradation of poly- and monocyclic aromatic radicals in combustion systems which would otherwise react with fuel components to form polycyclic aromatic hydrocarbons (PAHs) and eventually soot. Despite intense theoretical and experimental scrutiny over half a century, the overall reaction channels h...
conclusions we have developed a new, simple, and efficient method for one-pot aminoalkylation of active phenol compounds with various imines prepared from 2-aminopyrimidine and benzaldehydes in good to high yields (40%-97%). materials and methods all starting materials were purchased from merck and aldrich companies. the ir spectra were recorded on a perkin-elmer rxi infrared spectrometer. resu...
Cowberry (Vaccinium vitis-idaea L., family Ericaceae) is a small evergreen shrub found in the herbaceous layer of circum boreal forests Northern Eurasia and North America. It sometimes cultivated, mainly gardens, but more commonly its edible fruits are collected from native habitats. Chemical composition different aerial parts Vaccinium phenol glycosides, phenyl propanoids, anthocyanins, saponi...
