  Synthesis, structures and ε-caprolactone polymerization activity of aluminum N,N′-dimethyloxalamidates

  摘要：

  Alkyl aluminum N,N'-dimethyloxalamidates R(4)Al(2)(dmoa) (1, R = Me; 2, R = Et; 3, R = (i)Bu; 4, R = (t)Bu) (dmoa-H(2) = N,N'-dimethyloxalamide) have been prepared and characterized. Molecular structures of the compounds 1 and 4 have been determined by X-ray crystallography. The centrosymmetric molecules of the compounds consist of one N,N'-dimethyloxalamidate unit bonded to two four-coordinated aluminum atoms. Each of the aluminum atoms is bonded to two alkyl groups, and oxygen and nitrogen atoms originating from two different amidate groups. A skeleton framework of the molecules of 1 and 4 consists of two fused AlNOC(2) heterocyclic rings, which are flat and positioned in one plane. It was shown that compounds 1-3 were initiators in a process of ring opening polymerization (ROP) of epsilon-caprolactone. The compound 4 exhibited low activity in ROP. (C) 2010 Elsevier B.V.
