Paragraph 0017; 0030; 0031, (2018/02/04)
The invention relates to a preparation method for 4-(chlorodifluoromethoxy)aniline. The method includes: taking trichloromethoxybenzene as the raw material, employing hydrogen fluoride to conduct selective fluorination to obtain chlorodifluoromethoxybenze

experimental part, p. 2875 - 2880 (2009/04/07)
Both alkyl and aryl chlorothioformates could readily be obtained from the corresponding alcohols and thiophosgene. These families of compounds were treated with BrF3 to form the corresponding alkyl and aryl chlorodifluoromethyl ethers in 60-85% yields. The method is suitable for constructing a variety of aliphatic as well as electron-deficient aromatic chlorodifluoromethyl ethers. The reactions proceed under mild conditions and short reaction times. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
Process for the preparation of aromatic compounds which contain perfluorinated side-chains bonded via a heteroatom
-
, (2008/06/13)
Aromatic compounds which contain perfluorinated side-chains bonded via a heteroatom are prepared by treating aromatic compounds, which contain side-chains which are perhalogenated, but only partially fluorinated, and bonded via heteroatom, with a catalyst capable of transferring halogen atoms.
