| 摘 要： | 本文用自旋捕捉技术与ESR相结合的方法,研究取代环戊二烯钛络合物(RC5H4)2TiCl2(R=H,CH3,C2H5,C3H7,C5H11,C6H11)光解的活泼自由基。结果表明,光解初级过程是Ti-(RC5H4)π键均裂,以生成(RC5H4)·和(RC5H4) TiCl2。(RC5H4)·可为ND捕捉,并生成两种自由基加合物,其浓度比约为1:1。

| Abstract: | The active radicals produced in the photolysis of substituted titanocene dichloride complexes (RC5H4)2TiCl2 (R=CH3 C2H5, C3H7, C5H11, C6H11) have been studied by combination of spin trapping technique with ESR spectroscopy Results show that the primary process of photolysis is homolytic cleavage of the Ti-RC5H4 π bond, with the formation of (RC5H4)· radical and (RC5H4) TiCl2 fragment. The (RC5H4)· radical can be trapped by nitrosodurene (ND) to form two spin adducts and their concentration ratio is about 1:1. |
