General description

Rotational Raman spectra of 1,3,5-trifluorobenzene has been studied under high resolution using a single mode argon laser as the exciting source. Proton and fluorine magnetic resonance spectra of 1,3,5-trifluorobenzene in a nematic liquid crystal has been analyzed.

Application

1,3,5-Trifluorobenzene was used in the synthesis of (−)-epicatechin and its 3-O-gallate.

Concise synthesis of (-)-epicatechin and its 3-O-gallate is described, illustrating efficacy of the new strategy for catechin-class polyphenols based on assembly of lithiated fluorobenzene and epoxy alcohol followed by a pyran cyclization. 1,3,5-Trifluorobenzene serves as the A-ring equivalent for functionalization
