4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of 4-Hydroxy-3-methoxyphenethanol

The nickel-catalyzed direct borylation and silylation of phenolic esters has been established. The key to this highly efficient acyl C-O bond borylative and silylative cleavage depends on the appropriate choice of different ligands and additives in the presence of nickel catalyst. Both transformations exhibit good functional group compatibility and can serve as powerful synthetic tools for late-stage functionalization of complex compounds The elucidation of key mechanistic features of this newly developed acyl C-O bond activation in esters was confirmed by two well-characterized organonickel(II) intermediates.

2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1) belongs to ethers.

Decarboxylative Benzylation of Aryl and Alkenyl Boronic Esters was written by Moon, Patrick J.;Fahandej-Sadi, Anis;Qian, Wenyu;Lundgren, Rylan J.. And the article was included in Angewandte Chemie, International Edition in 2018.COA of Formula: C12H17BO3 The following contents are mentioned in the article:

The copper-catalyzed decarboxylative benzylation of aryl and alkenyl boronic esters with electron-deficient aryl acetates is reported. The oxidative coupling proceeds under mild, aerobic conditions and tolerates a host of potentially reactive electrophilic functional groups that would be problematic with traditional benzylation methods (aryl iodides and bromides, protic heteroatoms, aldehydes, Michael acceptors). A reaction pathway in which a benzylic nucleophile is generated by aryl acetate decarboxylation and in turn is intercepted by the catalyst to form diarylmethane products is supported by mechanistic studies. This study involved multiple reactions and reactants, such as 2-(3-Methoxyphenyl)-5,5-dimethyl-1,3,2-dioxaborinane (cas: 1003858-50-1COA of Formula: C12H17BO3).

Liang, Yuwei et al. published their research in Chinese Journal of Chemistry in 2022 | CAS: 109-85-3

2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Computed Properties of C3H9NO

Water-soluble BOPAHY fluorophores have not yet been reported. The potential of 1,2,3-triazolium salts for the formation of water-soluble chromophores is explored. 1,2,3-Triazole-substituted pyrroles were synthesized in a metal-free pathway and alkylated to obtain water-soluble 1,2,3-triazolium BOPAHY dyes. High fluorescence quantum yields were observed for triazole-bridged BOPAHY dyes in DCM and moderate fluorescence quantum yields for 1,2,3-triazolium-bridged BOPAHY chromophores in DCM and H2O. The fluorescence of the freely rotatable 1,2,3-triazolium-linked BOPAHYs is partially quenched in H2O.

In the inverse electron-demand Diels-Alder (iEDDA) reactions between tetrazines and strained alkenes, a mixture of 1,4-dihydropyridazine isomers are formed first, and they are then oxidized to pyridazines.

In this study, 1,4-dihydropyridazines formed in the iEDDA reactions were oxidized to pyridazines by simply irradiating with an UV light under an air atm.
