of the photochemistry of (n5-C5Me5)Fe(CO)2R complexes, R = Me, Et, CH2CH2SiMe3 and SiMe3, which relate to a proposed mechanism for hydorsilation catalysis. These are (i) photochemically induced insertion of C2H4 into the Fe-Si bond of (n5-C5Me5)Fe(CO)2SiMe3, (ii) transfer of either the -SiMe3 group or a beta-H group upon photolysis of n5-C5Me5)Fe(CO)2CH2CH2SiMe3, and (iii) reductive elimination of alkane
摘要 : 我们希望报告 (n5-C5Me5)Fe(CO)2R 配合物的光化学的三个方面,R = Me、Et、CH2CH2SiMe3 和 SiMe3,它们与所提出的氢化硅烷化催化机制有关。它们是 (i) 光化学诱导 C2H4 插入 (n5-C5Me5)Fe(CO)2SiMe3 的 Fe-Si 键中,(ii) 在 n5-C5Me5 光解时转移 -SiMe3 基团或β-H 基团)Fe(CO)2CH2CH2SiMe3,和 (iii) 在光诱导氧化加成 HSiR'3 (R' = Me, Et) 到 n5-C5Me5)Fe(CO)2R, R = Me, Et 后,烷烃 RH 的还原消除.
