Zeroth-order regular approximation (ZORA) density functional theory (DFT) calculations of one-bond X–F indirect nuclear spin-spin coupling () tensors were performed on a series of fluorine-containing compounds covering several valence shell electron pair repulsion (VSEPR) theory geometries for which...
Herein we present a general protocol for the functionalization of biomolecules with an organotrifluoroborate moiety so that they can be radiolabeled with aqueous18F fluoride (18F−) and used for positron emission tomography (PET) imaging. Among the β+-emitting radionuclides, fluorine-18 (18F) is...
S9). In positive-ion mode, a primary loss of HF, i.e., directly from the protonated or deprotonated molecule selected as precursor ion in MS–MS, is often observed, although in some case in competition with the loss of water. Some typical examples are discussed here (structures in Fig....
Following parenteral administration, the onset of action of GC is strongly linked to the pharmacomodulation of the molecule. Thus, water-soluble derivatives such as phosphates or hemisuccinate have an immediate action start. On the contrary, esters or acetonides have a delayed effect with a ...
The nuclear magnetic resonance spectra of a number of dibenzofulvenes, fluorenylidenephosphoranes, and dibenzoheptafulvenes have been studied, and the effect of the following factors has been evaluated: (i) the planarity of the molecule;... M Rabinovitz,I Agranat,ED Bergmann - 《Journal of th...
In the title compound, C15H15NO4, the whole molecule, except for the dioxolane ring, adopts a nearly planar conformation. The dioxolane ring, which has an envelope conformation, is mainly situated on the si,si diastereotopic face of the olefinic bond. In the crystals of the title compound,...
