This led to an assumption that binding was influenced by the acidity of the phenolic proton. Further investigation shifted to hIYD as described below. TABLE 1. hIYD affinity for halotyrosines Halotyrosine derivativeKDpKab (2-halophenol) hIYDmIYDa μm I-Tyr 0.15 ± 0.04 0.090 ± 0.04 8.53...
A first-order four-body perturbation theory is developed to calculate both the differential and integral cross-sections for K-shell charge exchange from multi-electron atomic targets to the 1s bound state of the fast proton projectiles. The correct boundary conditions are incorporated in the formalism...
During expansion of mechanistic networks, the program generally uses the individual steps, e.g., imine formation is divided into 1) ketone protonation, 2) imine addition to the protonated ketone, 3) proton transfer from nitrogen to oxygen, 4) formation of an iminium cation via elimination of ...

Proton-coupled electron-transfer oxidation of phenols by hexachloroiridate(IV). One-electron oxidation of phenol, 2,4,6-trimethylphenol, and 2,6-dimethylphenol by [IrCl(6)](2-) in aqueous solution has a simple pH dependence, indicating... N Song,DM Stanbury - 《Inorganic Chemistry》 被引量...
Among the several proton and Lewis acids employed in attempts for deprotection, treatment of 151b in cone. HCl / MeOH provided a mixture of four spiroethers (152, 153, 154, and 155) which was not accompanied by the deprotected 151d. The stereoisomers were readily separated by preparative ...
