Abstract:In einer friiheren Mitteilung2) berichteten wir iiber die Darstellung von Carboxyphosphinen, die aus o-Halogen-carbondure-athylestern und Alkali-phosphiden und anschliedender alkalischer Verseifung entstanden waren. Diese Reaktionen verliefen jedoch nur bei Verwendung von Natrium-bzw. Kalium-diphenylphosphid unter Substitution des Halogens durch den ,,Diphenylphosphidrest" (CjH5)2P-einheitlich. Bei den Umsetzungen des Lithium-diathyl-bzw. dicyclohexyl-phosphids mit Halogencarbonsaure-athylestern wurde einmal e… Show more

“…New and fundamentally different routes to the cyclopolyphosphine moiety are represented by the dehydration of a primary phosphine oxide (69) 4C6H5PH2 + 4R2Hg -(C6H6P)4 + 4Hg + 8RH Useful yields of cyclopolyphosphines have also been obtained by heating simpler molecules such as (CF3)4P2 and (CF3)2PH (117) and by reaction of metal organophosphides of the type RPHM with organic dihalides (78) and bromine (80).…”

The title compound was synthesised in moderate yield via stereoselective self-assembly of two bisphosphine, four formaldehyde and two primary amine molecules.
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.
