Photoinitiation of acrylate polymerization by [Cr(eta6-arene)(CO)3] complexes in the presence of an organic chloro compound was investigated. For the bimolecular system, a good correlation between activity and metal-arene and metal-carbonyl bond strength was observed. The highest efficiency was found for an initiator in which the organic chloro compound was tethered to the complexed arene: [Cr(eta
研究了在有机氯化合物存在下通过 [Cr(eta6-arene)(CO)3] 配合物光引发丙烯酸酯聚合。对于双分子系统,观察到活性与金属-芳烃和金属-羰基键强度之间的良好相关性。发现有机氯化合物与络合芳烃相连的引发剂效率最高:[Cr(eta6-C6H5CH2OCOCCl3)(CO)3]。探索了光引发的初始步骤,并为 Cr(eta2-丙烯酸酯)(eta6-芳烃)(CO)2 络合物中的金属-芳烃键断裂提供了证据。
