The characterisation and reactivity of (η5-C5H5)M(CO)3(Xe) (M = Nb or Ta) in solution at room temperature
摘要:
Employing fast time-resolved infrared (TRIR) spectroscopy we
have characterised CpM(CO)3(Xe) (M = Nb or Ta) at room
temperature in supercritical Xe solution; CpM(CO)3(Xe) were
found to exhibit a similar reactivity with CO to the corresponding alkane
complexes, CpM(CO)3(n-heptane) and we report a trend in
reactivity of the early transition metal Xe complexes.
