Abstract
The chelation dynamics of [5-C5H4C(O)R]Mn(CO)3 complexes 1 (R = CH2(SCH3)3), 2 (R = CH(SCH3)2), and 3 (R = C(SCH3)3) in room temperature acetonitrile solution have been investigated on the picosecond timescale by UV-pump IR-probe transient absorption spectroscopy. Similar to the previously observed behavior in n-heptane solution, irradiation of 3 in acetonitrile at 289 nm induces CO loss to exclusively yield the Mn-S chelated (ring-closed) product in
