Associative substitution reactions in 17 electron organometallic radicals: direct observation of the reaction of [(C5H5)Fe(CO)2]· with P(OMe)3 using very fast time-resolved i.r. spectroscopy
Abstract
Time-resolved i.r. spectroscopy is used to monitor directly the formation of [(C5H5)Fe(CO)P(OMe)3]· in the reaction of P(OMe)3 with [(C5H5)Fe(CO)2]·, generated by 351 nm photolysis of [{(C5H5)Fe(CO)2}2] in n-heptane solution at room temperature; the reaction is an associative process with a bimolecular rate constant of 8.9 ± 2.0 × 108 dm3 mol–1 s–1.
