Although metal-free cycloadditions of cyclooctynes and azides to give stable 1,2,3-triazoles have found wide utility in chemical biology and material sciences, there is an urgent need for faster and more versatile bioorthogonal reactions. We have found that nitrile oxides and diazocarbonyl derivatives undergo facile 1,3-dipolar cycloadditions with(More)
We have investigated the reaction of Re(dmb)(CO)(3)COOH with CO(2) using density functional theory, and propose a mechanism for the production of CO. This mechanism supports the role of Re(dmb)(CO)(3)COOH as a key intermediate in the formation of CO. Our new experimental work supports the proposed scheme.
The biochemical properties of nitroxyl (HNO/NO(-)) are distinct from nitric oxide (NO). Metal centers, particularly Fe, appear as suitable sites of HNO activity, both for generation and targeting. Furthermore, reduced Fe-NO(-)/Fe-HNO or {FeNO}(8) (Enemark-Feltham notation) species offer unique bonding profiles that are of fundamental importance. Given the(More)
The reactivity of free NO (NO(+), NO(•), and NO(-)) with thiols (RSH) is relatively well understood, and the oxidation state of the NO moiety generally determines the outcome of the reaction. However, NO/RSH interactions are often mediated at metal centers, and the fate of these species when bound to a first-row transition metal (e.g., Fe, Co) deserves(More)
Whereas photon coincidence spectroscopy is a promising technique for probing the nonlinear regime of cavity quantum electrodynamics in the optical domain, the accuracy is mitigated by two factors: higher–order photon correlations, which contribute to an enhanced pair count rate, and non– simultaneity of emitted photon pairs from the optical cavity. We show(More)
We show that photon coincidence spectroscopy can provide an unambiguous signature of two atoms simultaneously interacting with a quantised cavity field mode. We also show that the single–atom Jaynes–Cummings model can be probed effectively via photon coincidence spectroscopy, even with deleterious contributions to the signal from two–atom events. In(More)
The selective reduction of nitrite (NO2(-)) to nitric oxide (NO) is a fundamentally important chemical transformation related to environmental remediation of NOx and mammalian blood flow. We report the synthesis and characterization of two nonheme Fe complexes, [Fe(LN4(Im))(MeCN)2](BF4)2 (1(MeCN)) and [Fe(LN4(Im))(NO2)2] (2), geared toward understanding the(More)
