A PROCESS FOR THE PRODUCTION OF COMPOUNDS CONTAINING ALIPHATICALLY BOUND AMIDE OR URETHANE GROUPS ABSTRACT OF THE DISCLOSURE Compounds containing aliphatically bound amide groups or ure- thane groups are produced by reacting at least one compound containing an aliphatically bound ester or carbonate group with at least one compound containing at least one aliphatically bound amine group. This reaction is carried out in the presence of a catalytically active quantity of at least one alkali metal alkylate and at least one alkyl formate. These compounds are particularly useful as chain extending agents in the polyisocyanate addition process.
