Japanese Patent JP2003502491
Kind Code:
A
Abstract:
Process for the preparation of a condensation compound by reaction of at least one functional group of a first low-molecular weight compound having at least two functional groups, with at least one functional group of at least one further, second low-molecular weight compound having at least two functional groups, and which can be identical to the first or different from the first low-molecular weight compound, with obtainment of a condensation compound, characterized in that at least one of the functional groups involved in this reaction has been activated before the reaction by reaction with a compound of the following structure (I)where R' is a halogen atom or a radical (I')and where R1, R2, R1' and R2' are identical or different and are hydrogen, straight-chain or branched-chain alkyl, aryl, cycloalkyl, heterocyclic or aralkyl radicals having up to 30 C atoms, or either R1 and R2 or R1' and R2' or both R1 and R2 and R1' and R2' are linked to give a carbocycle or a heterocycle.
