Hydrogen Atom Abstraction from Hydrocarbons by a Copper(III)-Hydroxide Complex
With the aim of understanding the basis for the high rate of hydrogen atom abstraction (HAT) from dihydroanthracene (DHA) by the complex LCuOH (1; L = N,N'-bis(2,6-diisopropylphenyl)-2,6-pyridinedicarboxamide), the bond dissociation enthalpy of the reaction product LCu(H2O) (2) was determined through measurement of its pK(a) and E(1/2) in THF solution. In so doing, an equilibrium between 2 and ...
متن کاملFrom Abstraction to Realization
Prototypes One of the truly powerful tools in usage-centered design is the abstract prototype [Constantine, 1998; Constantine & Lockwood, 1999]. An abstract prototype allows designers to describe the contents and overall organization of a user interface without specifying its detailed appearance or behavior; it is, thus, a model of the architecture of the user interface being designed. We and o...
متن کاملOn Full Abstraction for PCF: I, II, and III
We present an order-extensional, order (or inequationally) fully abstract model for Scott's language pcf. The approach we have taken is very concrete and in nature goes back to S. C Kleene (1978, in ``General Recursion Theory II, Proceedings of the 1977 Oslo Symposium,'' NorthHolland, Amsterdam) and R. O. Gandy (1993, ``Dialogues, Blass Games, Sequentiality for Objects of Finite Type,'' unpubli...
متن کاملMinimal dark matter in type III seesaw
We explore the possibility of a new dark matter candidate in the supersymmetric type III seesaw mechanism where a neutral scalar component of the Y= 0 triplet can be the lightest supersymmetric particle. Its thermal abundance can be in the right range if non-standard cosmology such as kination domination is assumed. The enhanced cross-section of the dark matter annihilation to WW can leave dete...
متن کاملX-ray magnetic circular dichroism (XMCD) study of a methoxide-bridged Dy(III)-Cr(III) cluster obtained by fluoride abstraction from cis-[Cr(III)F2(phen)2](+).
An isostructural series of dinuclear chromium(III)-lanthanide(III) clusters is formed by fluoride abstraction of cis-[CrF2(phen)2](+) by Ln(3+) resulting in LnF3 and methoxide-bridged Cr-Ln clusters (Ln = Nd (1), Tb (2), Dy (3)) of formula [Cr(III)(phen)2(μ-MeO)2Ln(NO3)4]·xMeOH (x = 2-2.73). In contrast to fluoride, methoxide bridges in a nonlinear fashion, which facilitates chelation. For 3, X...
