SYNTHESIS OF URETHANES AND OF POLYURETHANES CATALYSED BY CARBENES
摘要
The present invention relates to a process for preparing a compound comprising at least a urethane group —HN—C(═O)—O, said process comprising a step (E) in which a compound (I) comprising at least an isocyanate functional group —N═C═O is reacted with an organic compound (II) carrying at least a hydroxyl group —OH, said reaction being carried out in a presence of a carbene (III) used as a catalyst.
