ChemInform Abstract Reaction of the 2-chloro-2-methylpropaneimidoyl chlorides (Ia) and (Ib) with triethyl phosphite (II) gives the imidoyl phosphonates (IIIa) and (IIIb), whereas the dehydrochlorination product (IV) is obtained from (Ic) and (II).
246ChemInform Abstract The imidoyl chloride (IV) is prepared from trifluoroacetylbenzamide (III) and phosphorus pentachloride. Reaction of (IV) with the trialkyl phosphites (V) gives the benzoyliminophosphonates (VII) via the intermediate pentacoordinated phosphorus compounds (VI). (1H-, 31P-NMR-, IRdata).
Die Chlorphosphite (I) reagieren mit den Carbonsäureamiden (II) und (IV) in Abhängigkeit von der Natur der Carbonsäure zu den Amidophosphiten (III) oder den Imidoylphosphiten (V).
Die dimere Verbindung (I) reagiert mit primären oder sekundären Aminen, z.B. (II), zu der in der trans‐Form vorliegenden Verbindung (III), die man auch aus Chlorcyclohexanon (IV) erhält.
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.
