✦ Synopsis

Abstract

The new type of α‐alkenyl esters of phosphorus acids containing ammonium or phosphonium groups in unsaturated radicals as well as carbonyl or other complexes of Mo, Cr, W, Mn, or Pt with such organophosphorus ligands have been described. The alkenyl phosphates undergo dealkylation upon heating to give betaines. This conversion results in a substantial decrease of an anticholinesterase activity of the compounds and in a sharp rise of their hydrolytic stability. The prototropic rearrangement is observed for the phosphonium betaines.

Hydrated multibilayers of 1-palmitoyl-2-monobromopalmitoyl-sn-glyeero-3-phosphorylcholine (BrDPPC), where the 2-chain is brominated at either the C-9 or C-10 position, have been studied by low and wide angle X-ray diffraction methods. Oriented and unoriented samples were investigated. The long spaci
