Fluoro- or trifluoromethyl-substituted benzyl and phenethyl alcohols: Substrates for metal-mediated site-selective functionalization was written by Marzi, Elena;Spitaleri, Andrea;Mongin, Florence;Schlosser, Manfred. And the article was included in European Journal of Organic Chemistry in 2002.Computed Properties of C9H9F3O This article mentions the following:
It was possible to functionalize the three fluorobenzyl alcs. and the three 2-(fluorophenyl)ethanols by metalation and subsequent carboxylation, the prototype electrophilic trapping reaction. Triisopropylsilyl (TIPS) outperformed methoxymethyl (MOM) as an O-protective group making seven new fluorobenzoic acids, including I and II, accessible in 63% average yield. The TIPS group tolerates weakly basic and acidic media and may facilitate further structural elaboration. The unprotected alcs. reacted more sluggishly and were unable to provide two of the targeted products. The yield averaged only 46% in the five other cases. The direct metalation of fluorinated benzyl and phenethyl alcs. remains nevertheless an attractive option because of its operational simplicity. All three (trifluoromethyl)benzyl alcs. and two of the three (trifluoromethyl)phenethyl alc. isomers were successfully submitted to the metalation/functionalization sequence. These five starting materials gave rise to a total nine new benzoic acids or lactones, e.g. III. Despite the poor yields (31% on average), the employed organometallic methods are extremely regioselective, economical and easy to perform. In the experiment, the researchers used many compounds, for example, 2-(4-(Trifluoromethyl)phenyl)ethanol (cas: 2968-93-6Computed Properties of C9H9F3O).
2-(4-(Trifluoromethyl)phenyl)ethanol (cas: 2968-93-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Computed Properties of C9H9F3O
