Thermal and photochemical reactions of sodium salts of P-phosphono tosylhydrazones have been investigated. When the sodium salt of dimethyl a-acetylmethylphosphonate tosylhydrazone is heated, the dimethoxyphosphonyl anior , though a relatively strong base, was eliminated. On the other hand, ultraviolet irradiation of the sodium salts of P-phosphono tosylhydrazones leads to dimethoxyphosphonyl-substituted olefins, presumably via the carbene intermediate. Some of the products result from a previously unreported phosphonyl group migration to a carbene.
Aus Cholesterin erhält man über (Ia) durch Epoxidierung zu (II), Reduktion zu (III), Acetylierung und Bromierung die Verbindung (IVa), die bei der Behandlung mit Ozon an Silicagel zu (IVb) hydroxyliert wird.
Bei der Thermolyse des Phosphono‐tosylhydrazon‐Anions (I) erhält man die Reaktionsprodukte (II)‐(IX), deren Bildungsmechanismen sowie Anteile bestimmt werden.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
