  摘要：

  M(CO){sub 6} 和 (NBD)M(CO){sub 4}（NBD = 降冰片二烯）的紫外激光闪光光解分别用于生成中间体 M(CO){sub 5}(s) (s = 正庚烷；M = Cr、Mo 和 W) 和 ({eta}{sup 4}-NBD)M(CO){sub 3}(s) fac 和 mer 异构体；M = Mo 和 W。然后使用快速 ({μ}s) 时间分辨 IR 光谱来测量这些中间体与可能是催化氢化混合物组分的物种（例如，H{sub 2}， NBD、CO 等）。测量表明，对于特定的中间体，与 H{sub 2} 和​​ NBD 的反应速率非常相似。因此，在典型的催化反应混合物中，中间体比 H{sub 2} 更可能与 NBD 反应，因为 NBD 的浓度明显高于 H{sub 2} 的浓度。傅里叶变换 IR 用于监测室温下光催化氘化过程中溶液中存在的羰基物质。这些包括以前未知的复合物 fac-

  Photochemically activated [MO(CO)(6)] and [MO(CO)(4)(eta(4)-nbd)] have been demonstrated to be very effective catalysts for hydrosilylation of norbornadiene (nbd) by tertiary (Et3SiH, Cl3SiH) and secondary (Et2SiH2 and Ph2SiH2) silanes to give 5-silyl-2-norbornene, which under the same reaction conditions transform in ring-opening metathesis polymerization (ROMP) to unsaturated polymers and to a double hydrosilylation product, 2,6-bis(silyl)norbornane. The yield of a particular reaction depends very strongly on the kind of silane involved. The reaction products were identified by means of chromatography (GC-MS) and 1 H and C-13 NMR spectroscopy. In photochemical reaction of [MO(CO)(4)(eta(4)-nbd)] and Ph2SiH2 in cyclohexane-d(12), eta(2)-coordination of the Si-H bond to the molybdenum atom is supported by H-1 NMR spectroscopy due to the detection of two equal-intensity doublets with (2)J(H-H) = 5.4 Hz at delta 6.12 and -5.86 ppm.
