Summary of "Functionalized Fluorophosphonium Ions."

Efforts to prepare an elusive donor-free phosphenium ion, [R2P]+, led us to synthesize functionalized fluorophosphonium cations of the type [R2P(F)X]+ (X = SiEt3, H, F), which were obtained from the related neutral fluorophosphines R2PF and R2PF3 upon protonation and reaction with solvated [Et3Si]+ ions (R = 2,6-Mes2C6H3). The hypothetical reductive elimination of [R2P(F)SiEt3]+ and [R2P(F)H]+ affording [R2P]+, Et3SiF and HF, respectively, was calculated to be endothermic by 40.1 and 190.6 kJ mol-1.

Medical and Biotech [MESH] Definitions

The movement of ions across energy-transducing cell membranes. Transport can be active, passive or facilitated. Ions may travel by themselves (uniport), or as a group of two or more ions in the same (symport) or opposite (antiport) directions.

An enzyme that catalyzes the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane ATPase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients.

Membrane proteins that allow the exchange of chloride ions for bicarbonate ions across the cellular membrane. The action of specific antiporters in this class serve important functions such as allowing the efficient exchange of bicarbonate across red blood cell membranes as they passage through capillaries and the reabsorption of bicarbonate ions by the kidney.

Bicarbonate transporters that move BICARBONATE IONS in exchange of CHLORIDE IONS or SODIUM IONS across membranes. They regulate acid-base HOMEOSTASIS, cell volume and intracellular pH. Members include CHLORIDE-BICARBONATE ANTIPORTERS (SLC4A1, 2, 3, and 9); SODIUM-COUPLED BICARBONATE TRANSPORTERS (SLC4A4 and 5, 7, 8 and 10); and a sodium borate cotransporter (SLC4A11 protein).

Proteins that cotransport hydrogen ions and phosphate ions across cellular membranes.
