Abstract

Procedure for carrying out ring closure reactions in high-boiling point solvents in the temperature range of 200 to 360ºC with separation of a partial molecule, characterized in that the starting compound is heated, molten or in solution in a solvent of appropriate high boiling point, and mixed with a larger amount, heated to 240 to 360ºC, of the high boiling point solvent, cyclization is carried out at the resulting mixing temperature of 200 to 350ºC and then the reaction mixture after which the product is recovered from the solvents.
