摘要：

Fast (nanosecond) time-resolved infrared spectroscopy has been used to follow the visible (532 nm) and UV (308 nm) flash photolysis of trans-[CpMo(CO)(3)](2) (Cp = eta(5)-C5H5), in n-heptane solution, at room temperature. With visible irradiation, the primary photoproducts observed, on this time scale, are CpMo(CO)(3) (major) and gauche-[CpMo(CO)(3)](2). The CpMo(CO)(3) radical dimerizes (k(2) = 3(+/-1) X 10(9) M(-1) S-1) to form both trans- and gauche-[CpMo(CO)(3)](2). The gauche-[CpMo(CO)(3)](2) isomer decays (k = 2(+/-0.5) X 10(2) s-(1) to the more stable trans isomer. Upon UV flash photolysis the GO-loss intermediate, Cp(2)Mo(2)(CO)(5), is observed as a primary photoproduct together with the CpMo(CO)(3) radical and gauche-[CpMo(CO)(3)](2).
