| abstract | PURPOSE: To readily obtain the subject compounds which are an intermediate for dyes, etc., in high selectivity in one step, by reacting phenols with aromatic carboxylic acids in the presence of a specific polysiloxane catalyst and passing the resultant product through an ester compound. n CONSTITUTION: Phenols are reacted with aromatic carboxylic acids in the presence of a polysiloxane catalyst having sulfonated phenyl groups as a catalyst in an amount within the range of 10W90mol. based on 100mol. phenols, normally at 100W400°C, especially 150W350°C to provide an ester compound, which is then subjected to the Fries rearrangement to afford the aimed compounds. The above-mentioned catalyst used is obtained by adding and reacting alcohols and dilute hydrochloric acid with a mixture of a phenyltrialkoxysilane with a tetraalkoxysilane, etc., and sulfonating the resultant polysiloxane having phenyl groups. n COPYRIGHT: (C)1989,JPO&Japio |
