Photolysis of M(CO)6, where M = Cr,Mo, and W, in Nujol mulls at 77K resulted in the formation of “free” CO and C4v M(CO)5 photoproducts. This reaction was found to be photochemically and thermally reversible. Similarly, the photolysis of the metal “half-sandwich” complexes (η6-C6H6)Cr(CO)3, (η5-C5H5)Mn(CO)3, (η5-CH3C5H4)Mn(CO)3 and (η5-C5H5)Re(CO)3 in Nujol at 77 K was found to form the corresponding
M(CO)6在Nukol藻中在77K时发生光解,其中M = Cr,Mo和W,导致“游离” CO和C 4 v M(CO)5光产物的形成。发现该反应是光化学和热可逆的。类似地,金属的光解的“半三明治”复合物(η 6 -C 6 H ^ 6)的Cr(CO)3,(η 5 -C 5 H ^ 5)的Mn(CO)3,(η 5 -CH 3 Ç 5 ħ 4)的Mn(CO)3和(η 5 -C 5 H ^ 5发现Nujol中77 K处的Re(CO)3形成相应的二羰基光产物和“游离” CO。发现这些反应是光化学可逆的。(η 6 -C 6 H ^ 6)的Cr(CO)3和(η 5 -C 5)的Re(CO)3,还发现直接在光解,以产生少量的双核的产品,而(η 5 -C 5 H ^ 5)的Mn(CO)3和(η 5 -CH 3 ç 5 ħ 4)的Mn(CO)3形成在退火类似物质。
