  气相有机金属催化：Fe(CO)3(C2H4)2 加氢乙烯的动力学和机理

  摘要：

  乙烯和氢气的惰性均相气相混合物加上催化量的 Fe(CO)/sub 5/ 在受到来自脉冲氮激光器的近紫外光照射后转化为活性乙烯加氢系统。存在于活性催化混合物中的有机金属物质通过傅里叶变换红外光谱进行识别和监测。催化反应之后是气相色谱，其提供乙烯和氢化产物浓度的量度。催化过程在利用光方面是有效的，典型的室温量子产率（每个吸收的光子形成的产物乙烷分子）为 20 或更多。吸收的激光产生 Fe(CO)/sub 3/(C/sub 2/H/sub 4/)/sub 2/ 的储库，通过失去一种高度不稳定的乙烯而发生热解离，从而产生活性催化剂，Fe(CO)/sub 3/(C/sub 2/H/sub 4/)。当去除光解光时，观察到催化活性下降，因为催化剂与游离 CO 结合形成稳定的 Fe(CO)/sub 4/(C/sub 2/H/sub 4/)。有机产物形成的速率与催化剂储层浓度成正比。乙烷生产的量子效率和 Fe(CO)/sub

  The reactions of Fe(CO)3 with ethylene and H-2 have been studied and rate constants for the formation of the H2Fe(CO)3 and Fe(CO)3(ethylene) complexes have been obtained. Further reactions of these unsaturated products with ethylene and H-2 respectively have been shown to lead to formation of the H2Fe(CO)3(ethylene) complex which is a crucial intermediate in the proposed mechanism for Fe(CO)3-induced hydrogenation of ethylene. The rate constants for formation of this complex from both precursors have been obtained and are reported along with the other rate constants determined in this study. Interestingly, though ethane is produced on a long time scale under the experimental conditions, H2Fe(CO)3(ethylene) is stable at room temperature in the approximately 100-mu-s observation time of these experiments. Significant differences have been observed for the rate constants of formation of the various complexes that were studied. These variations are discussed with respect to spin allowed versus disallowed reactions and the nature of the reacting ligand.

  The bond dissociation energy for loss of C2H4 from Fe(CO)(3)(C2H4)(2), produced by the reaction of C2H4 + Fe(CO)(3)(C2H4), has been determined as 21.3 +/- 2.0 kcal/mol. An estimate is made for a lower limit for the bond dissociation energy of Fe(CO)(4)(C2H4), which can be formed by reaction of CO + Fe(CO)(3)(C2H4) or Fe(CO)(4) + C2H4 with rate constants of (4.3 +/- 0.8) x 10(-12) and (1.7 +/- 0.2) x 10(-13) cm(3)/(molecule s) at 24 degrees C, respectively. The values for these bond dissociation energies are compared with those determined in prior studies of these systems. A new compound with infrared absorptions at 2147, 2091, and 2068 cm(-1) is best assigned as Fe(CO)(3)(C2F4)(2). A rate constant of (5.4 +/- 1.7) x 10(-12) cm(3)/(molecule s) at 24 degrees C is reported for the reaction of C2F4 with Fe(CO)(3)(C2F4) to form Fe(CO)(3)(C2F4)(2). Fe(CO)(4)(C2F4) can be formed by reaction of C2F4 and Fe(CO)(4), with a rate constant of (1.8 +/- 0.4) x 10(-14) cm(3)/(molecule s) at 24 degrees C. Infrared absorptions observed at 2135, 2074, and 2043 cm(-1) are assigned to this species. The relative stabilities of the mono- and bisethylene and perfluoroethylene compounds of iron are compared. Where possible, they are also compared to the corresponding chromium compounds and are discussed in the context of current concepts regarding metal-olefin bonding.
