6‐Thia‐1‐aza‐5λ5‐phosphabicyclo[3.2.0]hept‐3‐ene und Isothiocyanatophosphin‐sulfide aus (Methylidenamino)phosphinen, Schwefelkohlenstoff und Acetylen‐ oder Ethylen‐Derivaten

Abstract: Methy1idenamino)phosphines react with carbon disulfide to 1,3,2-thiazaphosphete derivatives 2. Acetylenedicarboxylates give with 2 6-thia-l-aza-5LS-phosphabicyclo[3.2.0]hept-3-enes 4a,b, and acrylates yield isothiocyanatophosphin-sulfides 5a-c. The structures of 4a and 5a are proven by an X-ray diffraction analysis. I_ Einleitung. -Die 1969-1970 erstmals hergestellten (Methy1idenamino)phosphine [2]beweisen ihre Ahnlichkeit mit Nitril-yliden in den Reaktionen mit Acetylen-und Ethylen-Derivaten [3]. Die zu 5H-1 … Show more

“…Moreover, small phosphorus‐chalcogen heterocycles that display asymmetry with respect to the 4‐membered core are even rarer. These include P‐S‐P‐E (Figure , G ), P‐Ch‐P‐C (Ch=S, Se, H ), P‐S‐C‐S ( I ), and P‐S‐C‐C structures ( J ), amongst others . Small ring cores that contain asymmetry in the presence of a P−P bond are by far the rarest, with published examples limited to only three species: P‐P‐C‐N ( K ), P‐P‐C‐O ( L ), and P‐P‐Si‐N ( M ) .…”
