Jiang, Jian-An; Chen, Cheng; Huang, Jian-Gang; Liu, Hong-Wei; Cao, Song; Ji, Ya-Fei published an article in 2014, the title of the article was Cu(OAc)2-catalyzed remote benzylic C(sp3)-H oxyfunctionalization for C=O formation directed by the hindered para-hydroxyl group with ambient air as the terminal oxidant under ligand- and additive-free conditions.Synthetic Route of 185345-46-4 And the article contains the following content:
A hindered para-hydroxyl group-directed remote benzylic C(sp3)-H oxyfunctionalization has been developed for the straightforward transformation of 2,6-disubstituted 4-cresols, 4-alkylphenols, 4-hydroxybenzyl alcs. and 4-hydroxybenzyl alkyl ethers into various aromatic carbonyl compounds The ligand- and additive-free Cu(OAc)2-catalyzed atm. oxidation-mediated by ethylene glycol unlocks a facile, atom-economical, and environmentally benign C=O formation for the functionalization of primary and secondary benzyl groups. Due to the pharmaceutical importance of 4-hydroxybenzaldehydes and 4-hydroxyphenones, the methodol. is expected to be of significant value for both fundamental research and practical applications. The experimental process involved the reaction of 3-Bromo-5-fluoro-4-hydroxybenzaldehyde(cas: 185345-46-4).Synthetic Route of 185345-46-4
The Article related to cresol alkylphenol hydroxybenzyl alc ether copper catalyzed benzylic oxyfunctionalization, hindered phenol oxidation air ethylene glycol ligand additive free, hydroxybenzaldehyde hydroxyphenone environmentally benign preparation and other aspects.Synthetic Route of 185345-46-4
