The utility of the Stern – Van Hook – Wolfsberg equation for vapour pressure isotope effects has been investigated. In addition, a plot of the equilibrium constant of the oxygen-18 exchange reaction vs. the mole fraction of pyridine presents no evidence of the formation of stoichiometric ...
However, the pyridine substituent prefers to sit in an axial position to maximize chelation with indium (Equation 47). The reaction also proceeds using pyridine-3-carbaldehyde to give the anti-allyl alcohol in high yield. (47) Diethyl zinc undergoes enantioselective addition to 2-pyridinecarbald...
Stage #1: 5-methoxy-N-[1-(pyridin-2-ylmethyl)-1H-indazol-5-yl]quinazolin-4-amine; pyridine hydrochloride In pyridine for 3h; Heating / reflux; Stage #2: With sodium hydrogencarbonate In water for 0.5h; Product distribution / selectivity;100% ...
In reaction equation (1), formula IV then stands for the compounds NaCN, KCN and Zn(SO2 R12)2. In this instance, the reaction in accordance with reaction equation (1) is carried out preferably in the temperature range of 60°-80°C. in a suitable organic solvent such as an alcohol, ...
The intracellular [Ca2+] was calculated according to the Grynkiewicz, Poenie and Tsien equation35. For measurements of [Ca2+] in intracellular stores primary cultured neurons and platelets were loaded with Rhod-2/AM (4 μM) or Mag-Fluo-4/AM (5 μM) for 1 h at 30 °...
in accordance 25 with the following equation: CH2=CH--CH2 CO O OH HCH- +NH=--CO O-CHs CH2-CH-CH2 CO \/ \CH -0 OH +HO20 GHi=OH-CH2a NH This new process for the manufacture of 2,4dioxo-3,3-dialkyl-6-methyl-tetrahydro - pyridines can only be carried out with the diallyl- ...
A weighted shear rate and saturation-dependent viscosity function is used to calculate the aqueous phase flow rate from the multiphase Darcy equation using conventional water relative permeability values. A similar approach can be applied to the hydrocarbon phase if one suspects the displaced phase is...
The percent inhibition of stimulated control is obtained using the following equation: ##EQU1## The abbreviation cpm is defined as counts per minute. Activity in the MLR screen recited above is indicative of usefulness of the active compound in the treatment of resistance to transplantation and...
A wide variety of solvents can be used for Equation A. These include water, lower alcohols, esters, ketones, methyl cyanoacetate, toluene, and xylene. It is also possible to operate without any solvent when either (II) or (III), or both, are liquids. Although the reaction proceeds in a...
We found that the calculated values of (x) were higher than unity, implying that one BPHP and TFPHP molecule replaces more than a water molecule at a constant temperature. On the other hand, the curve fitting of the El-Awady model is shown in Fig. 4c, d at different temperatures, ...
