| titleOfInvention | Method of synthesis of alcohol or phenol difluoromethyl esters |
| abstract | Usage: As components of liquid crystal compositions for electro-optical devices. Essence: an improved method for the preparation of difluoromethyl ethers or phenols of the general formula R — OCHPr, where R is lower alkyl, cyclohexyl. Alk - SvNyu - CeHto - CHa, Alk - SvZhO - SvN4CH2. RI - C “Nude. where Ri is Alk. Alk - SvN, R2 - CeN ", where: R2 - CN. Alk, Alk - SeN Alk - CBH4. Afk - SbNu - SvZhO, where Alk - SzNU, CsHn. Reagent 1: chlorodifluoromethane. Reagent 2: corresponding alcohol, Reaction conditions: two-phase system, temperature 20-60 °; C, catalyst: a mixture of quaternary ammonium hydroxide of the formula (8h) OH, where Rs SMz, C4Y9, go and try tritylbenzylammonium with three trimethylbenzylammonium chloride in a molar ratio of alcohol: quaternary ammonium hydroxide or trichloroethyltrimethylthenethyltriethylthenethylthenethylthenethylthenethylthenethylthenethylthenethisethyl : (0.6-1.3): {0.0002-0.002), in an organic solvent. The yield of the target product to 100%. New phycols of iclohexanol are obtained. 1 tab. yo yo |
