Though this chapter is focused on the °Th/U method, most of the concepts are directly applicable to other uranium-series chronometers, such as Pa/ U, Pa/ Th or Ra/ Mh. However, because the details of individual applications of these methods are more varied than for the Th/U method, and in some cases can be expected to evolve significantly (e.g., coupled Pa- °Th evolution Cheng et al. 1998), they will not be specifically addressed here.

In their outcomes, similar, but mechanistically different, coupling reactions were observed in the zincation of (tert-butyldimethylsilyl)(2-pyridinemethyl)amine (Scheme 75), which produced methylzinc(/ r/-butyldimethylsilyl) (2-pyridylmethyl)amide 113. Thermolysis of 113, or its treatment with one additional equivalent of dimethylzinc, yielded the C-G coupled dimer [l,2-bis(/ / -butyldimethylsilylamido)-l,2-dipyridylethane]bis(methylzinc) 114.170...

The toxicology-based conclusion that the minimum concentration for 2-nitrofluoranthene to be an important human cell mutagen is 1 p.g/g, coupled with air quality sampling data showing its concentrations in respirable particles sampled from ambient air can in fact reach 10 pg/g, provides a useful example of a productive symbiotic interaction between atmospheric chemists and toxicologists. Such interactions are essential for reliable risk assessments of air pollution and human health effects of complex combustion-generated mixtures of gases and particles. 

G-coupled proteins transduce a message from the external environment to the interior of the cell through a series of coupled molecular events. These have been described in chapter 2. 

The theory for cyclic voltammetry was developed by Nicholson and Shain [80]. The mid-peak potential of the anodic and cathodic peak potentials obtained under our experimental conditions defines an electrolyte-dependent formal electrode potential for the [Fe(CN)g] /[Fe(CN)g]" couple E°, whose meaning is close to the genuine thermodynamic, electrolyte-independent, electrode potential E° [79, 80]. For electrochemically reversible systems, the value of7i° (= ( pc- - pa)/2) remains constant upon varying the potential scan rate, while the peak potential separation provides information on the number of electrons involved in the electrochemical process (Epa - pc) = 59/n mV at 298 K [79, 80]. Another interesting relationship is provided by the variation of peak current on the potential scan rate for diffusion-controlled processes, tp becomes proportional to the square root of the potential scan rate, while in the case of reactants confined to the electrode surface, ip is proportional to V [79]. 

Cleavage of 3-hydroxykynurenine by kynureninase (step g, Fig. 25-11) forms 3-hydroxyanthranilate, which is opened under the action of another dioxygenase (step h) with eventual degradation to acetyl-CoA, as indicated. In insects the reactive 3-hydroxyanthranilate is utilized in "tanning" reactions, e.g., coupling to tyrosine residues to toughen insect cuticles and walls of cocoons.214... 

Polymerization by G—G Coupling. An aromatic carbon—carbon coupling reaction has been employed for the synthesis of rigid rod-like polyimides from imide-containing dibromo compounds and aromatic diboronic acids in the presence of palladium catalyst, Pd[P(C H4 (79,80). 

Experimental trends in Si shielding observed experimentally arise from variations in the coordination number (i.e. the number of atoms in the 1st coordination sphere), the extent of polymerization of the silicate tetrahedra, the degree of replacement of one net-work forming cation by another (e.g. coupled Na+, Al+3 for Si+4 substitution), the size of the rings of tetrahedra present and the Si-O-Si angles (1,2). Similar trends are seen in gas-phase molecules, species in aqueous solution and in both crystalline and amorphous solids. Polarized double-zeta basis set Hartree-Fock level calculations using small molecular cluster models reproduce these trends semiquantitatively, as we will show.
