| 中文摘要 | The gas-phase reactions of benzene and deuterated benzene (benzene-d(6)) with group VIB metal pentacarbonyls M(CO)(5) (M = Cr and W) and tetracarbonyl W(CO)(4) were probed with time-resolved infrared spectroscopy. Benzene reacts with M(CO)(5) forming presumably (eta(2)-benzene)M(CO)(5) in which benzene coordinates to the metal via an isolated double bond. The rate constants for reactions of C6H6 and C6D6 with Cr(CO)5 were found to be (3.0 +/- 0.7) and (3.3 +/- 0.2) x 10(13) cm(3) mol(-1) s(-1), respectively. The corresponding values with W(CO)(5) are (2.8 +/- 0.4) and (3.5 +/- 0.6) x 10(13) cm(3) mol(-1) s(-1). From the temperature dependence of rate of dissociative loss of benzene from (eta(2)-benzene)Cr(CO)(5), a bond dissociation energy of 9.2 +/- 0.8 kcal mol(-1) was determined for (eta(2)-benzene)Cr(CO)(5). The lower limit for bond dissociation energy for loss of the benzene ligand from (eta(2)-benzene)W(CO)(5) was estimated to be 11.7 kcal mol(-1). Benzene reacts with W(CO)(4) producing a species, presumably (eta(2)-benzene)W(CO)(4), which is stable in the millisecond time scale. The rate constants for reactions of C6H6 and C6D6 With W(CO)(4) were determined to be (3.5 +/- 0.2) and (4.1 +/- 0.4) x 10(13) cm(3) mol(-1) s(-1) respectively. Secondary addition of CO to (eta(2)-benzene)W(CO)(4) forms (eta(2)-benzene)W(CO)(5), and the rate constants are (9.4 +/- 0.9) and (8.7 +/- 1.0) X 10(11) cm(3) mol(-1) s(-1), respectively, for additions of CO to (eta(2)-C6H6)W(CO)(4) and (eta(2)-C6D6)W(CO)(4). |
