Preparation of Deuterium Labelled Organophosphonium Salts (Wittig Salts)
Hydrothermal Condition Catalyzed by Molecular Sieves. — Organophos49- 154 under
phonium salts are converted into deuterium-labeled ones under hydrothermal conditions in the presence of molecular sieves. The hydrothermal conditions can be obtained
by either heating D2O in an autoclave or irradiating with microwaves to D2O in a sealed
tube. This reaction is also applied to acetophenone (VII). — (YAMAMOTO, M.;
