Abstract The reaction of the aminoiminothiophosphoranes (1) with methanol yields the bisamino-thiophosphoric acid derivatives (3). la and IVb → VTb element halides form the new P-N element four membered rings 4 →7, which partially exist as a mixture of eis and trans isomers. Different ylide group transfer is observed on the reaction of la with trimethyl -phosphine or trimethyl phosphite. With trimethylphosphine (CH3)3P(S) and a phos-pha(III)azene are formed, with trimethyl phosphite (CH3O)3P = NC(CH3)3 and the [2 + 2] cycloaddition product of la and (R3C)(R3Si)N-P = S (R = CH3) can be isolated.
Für zehngliedrige Heterocyclen des Typs P4X6 kennt man nur adamantan‐artige Strukturen. Es wurde jetzt ein Gerüst der Zusammensetzung P2As2N6 synthetisiert, das erstmalig eine Struktur vom Tricyclo[4.2.1.12,5]decan‐Typ besitzt.magnified image
Über ein zweifach koordiniertes, dreibindiges Phosphoratom wurde eine Hydrazino‐Gruppe mit einer Imino‐Gruppe bei der Synthese des ersten Phosphatetrazens (1) – einer destillierbaren, grüngelben Flüssigkeit – verknüpft.
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.
