  Synthesis of caprolactamates of group II metals

  摘要：

  Caprolactamates of alkaline-earth metals and magnesium of the general formula[GRAPHICS] where M = Mg, Ca, Sr, and Ba, were synthesized from alkoxides, hydrides, and organometallic compounds of these metals and epsilon-caprolactam. The catalytic activities of caprolactamates obtained under conditions of anionic polymerization of epsilon-caprolactam were compared. It was demonstrated that the purest caprolactamates and, hence, the most effective catalysts of anionic polymerization of lactams can be obtained from organometallic and hydride compounds of these metals. The reactivities of alkoxides of the alkaline-earth metals and magnesium increase in metallation reactions of epsilon-caprolactam in the order Mg < Ca < Sr < Ba.

  The various synthetic routes to the magnesium di(epsilon-caprolactamate), CL2Mg, were investigated, primarily to establish reproducibility of the route and purity of the products. The reactions of epsilon-caprolactam, CL, with diethylmagnesium, Et2Mg, in diethyl ether have proved to be the most favourable preparative method. The products, primarily CL2Mg and CLnMg, the later representing CL2Mg solvated with (n-2) CL, were characterised by IR, Raman, mass and NMR spectroscopies, including methods of thermal analysis (TGA and DSC), and colligative properties of their benzene solutions were studied as well. A particular attention was paid to the reactions of the products with water. (C) 1998 Elsevier Science S.A. All rights reserved.
