The invention relates to lactamates of metals, in particular, to the preparation of magnesium di-lactamates, which are used as catalysts for anionic polymerization in polymeric chemistry. The goal is to increase the yield and quality of the target product. The method is carried out by the reaction of a lactam of the general formula HN- (CH 2 ) N CO, where N = 3-7, with an organomagnesium compound of the general formula MGR 2 , where R = C 2 H 5 , HC 3 H 7 or iso-C 3 H 7 , in diethyl ether or its mixture with toluene at 20-45 ° C for 1-2.5 hours. The method allows to obtain the desired product without impurities in 98% yield at room temperature against 40-160 ° C in the known case. 1 tab. |
