  Reaction kinetics of coordinatively unsaturated iron carbonyls formed on gas-phase excimer laser photolysis of iron pentacarbonyl

  摘要：

  The reactions of species produced on gas-phase excimer laser photolysis of Fe(CO)5 have been followed by transient infrared spectroscopy employing a diode laser probe. The initial photoproducts formed on 193-nm photolysis are identified as Fe(CO)2 and a product that is most likely Fe(CO). Both Fe(CO)2 and Fe(CO)3 are produced on 248-nm photolysis. Photolysis at 351 nm leads to the production of both Fe(CO)3 and Fe(CO)4. Species best assigned as excited states of Fe(CO)3 and Fe(CO)4 are observed to form as initial photoproducts following 248- and 351-nm photolysis, respectively. The magnitudes of the rate constants for reaction of the various coordinatively unsaturated metal carbonyls formed in this study with parent Fe(CO)5 or CO (summarized in Table I) are consistent with the hypothesis that spin-allowed reactions will be rapid while spin-disallowed reactions will be considerably slower. To provide further data in testing this hypothesis, the reaction of Fe(CO)4 with both O2 and H-2 has been measured.

  Reaction of [PPN][HFe(CO)4] (PPN = bis(triphenylphosphine)iminium) with PCl3 in a 1:1 ratio produced small amounts of [PPN][PFe(CO)4}2Cl2] ([PPN][Ia]). Reaction of [Et4N][HFe(CO)4] with AsCl3 in a 1:0.75 ratio in THF at −78 °C produced [Et4N][AsFe(CO)4}2Cl2] ([PPN][Ib]) as the majority product. The compound [PPN][(CO)4FePCl2O] ([PPN][II]) was obtained from the reaction of Fe2(CO)9 with PCl3 in THF

  transition metal carbonyl clusters, Fe3(CO)12 and Os3(CO)12, have been studied using ultrafast time-resolved infrared spectroscopy. In both the iron and osmium clusters, no trimetallic photoproducts containing bridging carbonyls appear to be formed upon 267 or 400 nm photolysis of nonbridged parent molecules. This directly contrasts with the results of observations made previously for the Ru3(CO)12 congener

  使用超快时间分辨红外光谱研究了两个8族过渡金属羰基簇Fe 3（CO）12和Os 3（CO）12的皮秒光化学动力学。在铁和簇中，在未桥接母体分子进行267或400 nm光解后，似乎没有形成含桥连羰基的三金属光产物。这与先前对Ru 3（CO）12的观测结果形成鲜明对比。同类物，其中非桥接母体络合物的光解仅导致含有桥连羰基的三金属光产物的形成。在本研究中，唯一的光解导致桥联羰基光产物的络合物是Fe 3（CO）12的桥联C 2 v异构体。对于铁簇，激发主要导致瞬态金属-金属键裂解光产物与Fe（CO）4和Fe 2（CO）8的混合，其寿命在皮秒级的时间范围内簇碎片产生的光产物。对于the簇，观察到相似的金属-金属裂解瞬态在皮秒级的时间范围内恢复，并且还观察到寿命更长的羰基损失络合物。结合有关钌同类物光化学的现有文献，这项研究的结果突出了第8组过渡金属簇光化学的细微差别。

  The photolysis of Fe(CO)3(η4-s-cis-1,3-butadiene) (1) and Fe(CO)4(η2-1,3-butadiene) (2), formerly studied in low-temperature matrixes, is reexamined in cyclohexane solution at ambient temperature using time-resolved IR spectroscopy in the ν(CO) region.
