摘要：
The invention relates to a method for preparing a compound comprising at least one β-hydroxy-urethane unit and/or at least one γ-hydroxy-urethane unit, consisting in reacting a compound (A) comprising at least one cyclocarbonate reactive unit with a compound (B) comprising at least one amino reactive unit (—NH2) in the presence of a catalyst. The invention also relates to the use of a catalyst comprising at least one organometallic complex and a co-catalyst chosen from the group of Lewis bases and/or tetra-alkyl ammonium salts, in order to catalyse the method of the invention. The invention relates to the technical field of preparing urethane derivatives.
