141 0‐Aryl‐O‐alkyl‐S‐(N‐alkylcarbamoylmethyl)‐dithiophosphate (III) erhält man S 0087 aus den Natriumsalzen von Amiden der Thioglykolsäure (II) und O‐Aryl‐O‐alkyl‐chlorthiophosphaten (I) in Methanol oder Äthanol bei 0°C ‐ 20°C (16 Stdn. Die Ausbeuten liegen zwischen 4 und 48%.
Die (O ,O‐Dialkyl‐dithio‐phosphory1)‐alkylcarbonsäure‐chloride (I) reagieren mit Thioglykolsäurehydrazid (II) hauptsächlich zu den phosphorylierten Acylthioglykolsäure‐hydraziden (III).
Hydrogen chloride (III), formed during the chlorination of dimethyl phosphite (I) to produce dimethyl chlorophosphate (II), reacts both with (I) and with (II) to give the compounds (IV) ‐ (VII).
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.
