“…In this work, the 2-allylphenols 158 were isomerized with 4 equiv of potassium tert -butoxide in tetrahydrofuran to give the corresponding isomeric analogues 159 , followed by acylation with acryloyl chloride in triethylamine to afford the dienes 160 . For an alternative synthesis of 2-(prop-1-en-1-yl)phenols, see refs and . These dienes, viz., 160 , were then ring-closed by application of the second generation Grubbs catalyst GII to afford a library of substituted coumarins 161 (Scheme ).…”

By triple condensation of 2-allylphenol with formaldehyde and methylamine (at a ratio of 1:1:1 and 1:2:1 mol, at 800C for 3 hours) a number of compounds (I-III) of various structures was prepared. It has been established that, depending on the ratio of the taken reagents, compounds of various structures are formed. By the reaction of compound I - 8-allyl-substituted 1,3-benzoxazine with HBr quaternary ammonium salt (IV) was obtained. Antimicrobial activity of 8-allyl-substituted 1,3-benzoxazine (I) and ammonium salt (IV) against microorganisms: Staphylococcus aureus NCTC 6571, Staphylococcus aureus ATCC®25923, Escherichia coli ATCC®25922, Candida albicans NSTC-3255/ATCC2091, Shigella flexneri ATCC®12022, Salmonella enterica ATCC®13076, and Aspergillus niger (aquatic isolate) was studied. It was found that compounds I and IV at a concentration of 30 mg/L in comparison with the references (amoxicillin and fluconazole) have the highest bactericidal and fungicidal properties. By thermal treatment of compound I cross-linked copolymer V was synthesized. While studying the thermal properties of copolymer V their sufficient thermal stability (up to ~4500C) was established. Copolymer V also has a sorption property for the extraction of uranyl ions from aqueous systems (the degree of extraction at pH 7 is ~70%, the sorption capacity – 178 mg/g). The structures of the obtained compounds were confirmed by IR and NMR spectroscopy

“…It is worth noting that alkenylphenol and their derivatives are functionally substituted organic compounds [29][30][31][32][33][34][35][36][37][38][39][40][41][42] that can be applied as effective corrosion inhibitors and biocides [28,[43][44][45]. Furthermore, such compounds can be used as light stabilisers for polymers [46], additives in mineral oils and fuels [47][48][49], to obtain photo-resisting materials [50,51]. Cationic forms of alkenylphenol derivatives are especially important as corrosion inhibitors and biocides, as they are highly soluble in water [28,44].…”

A series of 1-(4-(2-allylphenoxy)butyl)piperidin-1-ium halides (4a-d) was synthesized and characterized via spectroscopic methods (FTIR, 1 H NMR). The corrosion inhibition of the synthesized halides on carbon steel in water-salt-hydrocarbon environment, saturated with H2 S, was investigated. For this purpose, a series of techniques such as gravimetric measurement, potentiodynamic polarisation, and scanning electron microscope (SEM) were used and some thermodynamic parameters of corrosion process (Δ G ads. , ΔH 0 ads. , Δ S 0 ads. ) were evaluated. The steel surface was checked by SEM, and the steel surface showed good surface coverage. The results showed that the synthesized compounds at the concentrations 125, 150 mg ×L -1 have corrosion inhibition activity of 78%–95% by gravimetric measurements and 81%–92% by potentiodynamic measurements at 100, 150 mg ×L -1 . The biological activity was examined against sulphate-reducing bacteria (SRB). It was revealed that at the concentration of compounds 4c and 4d, 100 mg ×L -1 , the antibacterial activity was 100%.
