| titleOfInvention | Process for the manufacture of alkenylated hydroxylated aromatic compounds, of chroman compounds and of their acylated derivatives |
| abstract | The present invention relates to a process for the manufacture of alkenylated hydroxylated aromatic compounds, of chroman compounds and of their acylated derivatives. The processes of the present invention are characterized in that at least one step of the processes is carried out in the presence of an indium salt as the catalyst. Thus, an object of the present invention is the use of an indium salt as the catalyst in Friedel-Crafts alkylation reactions of aromatic compounds featuring at least one hydroxy group and ring-closure reactions of the latter to produce chroman-ring compounds in organic solvents. According to another aspect of the invention indium salts can be used as the catalyst in processes for the manufacture of tocyl alkanoates, tocopheryl alkanoates and alkanoates of aromatic compounds featuring at least one hydroxy group by reacting tocols, tocopherol and aromatic compounds featuring at least one hydroxy group, respectively, with an acylating agent. |
