Abstract:
Incorporation of the OCF3 group into organic molecules, especially aromatic and heteroaromatic compounds, is recognized as one of the major challenges in synthetic organic chemistry. Although many attempts have been made to develop efficient trifluoromethoxylation strategies, most of the current approaches still require use of highly toxic, thermally unstable reagents, or impractical reaction conditions. Herein, we highlight a recent contribution from our group towards the synthesis of (hetero)aryltrifluoromethyl ethers. Our protocol is scalable, operationally simple, and allows an easy access to a wide range of synthetically useful ortho-OCF3 aniline derivatives, as well as functionalized trifluoromethoxylated pyridines and pyrimidines under mild reaction conditions.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
