Abstract

The new 2-pyridinecarboxylate (2-pic) complex of chromium(III) has been designed and synthesized as a new highly active and selective oligomerization catalyst. The crystal structure of the new compound has been determined by X-ray diffraction. The composition and purity of [Cr(2-pic)(OH)]NO have been confirmed by several spectroscopic methods and the elemental analysis. Furthermore, the new complex has been investigated towards its catalytic activity for the oligomerization of 2-chloro-2-propen-1-ol under the atmospheric pressure and at room temperature. It has turned out that the novel catalyst exhibits a very high catalytic activity. Consequently, [Cr(2-pic)(OH)]NO belongs to a new generation of non-metallocene catalysts.

摘要

新型铬（III）的2 - 吡啶羧酸酯（2 - pic）配合物已被设计并合成出来，作为一种新型的高活性和选择性齐聚催化剂。通过X射线衍射确定了该新化合物的晶体结构。[Cr(2 - pic)(OH)]NO的组成和纯度已通过多种光谱方法和元素分析得到证实。此外，还研究了这种新型配合物在常压和室温下对2 - 氯 - 2 - 丙烯 - 1 - 醇齐聚反应的催化活性。结果表明，这种新型催化剂表现出非常高的催化活性。因此，[Cr(2 - pic)(OH)]NO属于新一代非茂金属催化剂。
