Interconversion Rates and Reactivity of <i>Syn</i>- and <i>Anti</i>-rotamers of Neutral and Cationic Molybdenum and Tungsten Imido Alkylidene <i>N</i>‑Heterocyclic Carbene Complexes
The interconversion rates of the syn- and anti-isomers of the neutral molybdenum and
tungsten imido
alkylidene N-heterocyclic carbene (NHC) complexes
of the general formula [M(NR)(CHCMe2R′)(NHC)(OR″)2] (M = Mo, W; R = adamantyl, 2,6-Me2-C6H3, 2,6-iPr2–C6H3, 2,6-Cl2–C6H3, 2-tBu-C6H4; NHC = 1,3-diisopropylimidazol-2-ylidene (IiPr),
1,3-dimethylimidazol-2-ylidene (IMe), 1,3-dicyclohexylimidazol-2-ylidene
(ICy), and 1,3-dimesitylimidazol-2-ylidene (IMes); R′ = Me,
Ph; R″ = CMe(CF3)2, CMe2(CF3), C(CF3)3, C6F5, SO2CF3) and of the cationic complex [Mo(N-2,6-Me2-C6H3)(CHCMe2Ph)(IMes)(SO3CF3)(CD3CN)+ B(3,5-(CF3)2C6H3)4–] were determined by irradiating
solutions of the catalysts with 366 nm UV light followed by recording
the back-isomerization of the anti- to the syn-isomer. Both the rate of anti to syn and syn to anti interconversion, ka/s and ks/a were found
to be orders of magnitude lower than in tetracoordinated, neutral
Schrock catalysts of the general formula [Mo(NR)(CHCMe2R′)(OR″)2]. Accordingly, the values for
the Gibbs free energy of the transition state, ΔG‡, are significantly higher for both neutral and
cationic molybdenum and tungsten imido alkylidene NHC complexes than
for Schrock catalysts. NMR investigations strongly suggest that these
higher ΔG‡ values are attributable
to dissociation of an anionic ligand from a neutral pentacoordinated
catalyst that precedes interconversion. As with Schrock catalysts,
the anti-isomer proved to be the more reactive isomer,
in both ring-opening metathesis polymerization and ring-closing metathesis
(RCM) reactions, allowing for higher productivities, expressed as
turnover numbers, in RCM

Kaplan-Meier (KM) curves for all-cause death rates, macrovascular event rates and T2DM-related hospitalizations for patients with either MET or SU monotherapy (PS matched groups). The figure shows KM curves representing the percentage of event-free patients (all-cause event as well as mortality, MACE and T2DM-related hospitalizations) for two T2DM-incident cohorts: patients who received SU monotherapy and patients who received MET monotherapy. Cohorts are matched by PSM. Observation started with the first observed SU/MET prescription. (TIF 546 kb
