N-Alkylated Pihydrazidophosphoric Acid Esters and Hexachlorocyclotriphosphaza-l,3,5-triene: Building Blocks of Spirocyclic SystemsIn contrast to secondary amines the N-alkylated di hydrazidophosphoric acid derivatives reported here attack hexachlorocyclotriphosphaza-l,3,5-triene exclusively at geminal positions and therefore react to spirocyclic systems. The synthesis and spectroscopic characterization of 4′,4′,6′,6′-tetrachloro-2-phenoxy-l,3,7,9-tetraaza-2λ5,8λ5-diphosphatricyclo[7.3.0.03.7]dodecane-spiro[8.2′]-cyclotri(phosphazene)-2-sulfide (Cl4N3P3(N(CH2)3N)2P(S)OC6H5) (1) and 4,4,6,6-Tetrachloro-l′,2′,4′,5′-tetramethyl-6′-phenoxycyclotri-(phosphazene)-spiro[2.3′]-cyclodi(λ5-phosphadiazane)-6′-sulfide (Cl4N3P3(NCH3NCH3)2P(S)OC6H5) (2) are described. The molecular structures of 1 and 4,4,6,6-Tetrachloro-1′5′-dimethyl-6′-phenoxycyclotri(phosphazene)-spiro[2.3′]-cyclodi(λ5-phosphadiazan)-6′-sulfide (Cl4N3P3(NHNCH3)2P(S)OC6U5) (3) were determined by X-ray single crystal structure analysis and show that the six-membered phosphorus-hydrazine rings of both compounds adopt twist-conformations.
Notes:
Im Gegensatz zu sekundären Aminen greifen die beschriebenen N-alkylierten Dihydrazidoderivate der Phosphorsäure Hexachlorcyclotriphosphaza-l,3,5-trien ausschließlich geminal an und reagieren daher zu spirocyclischen Systemen. Die Synthese und spektroskopische Charakterisierung von 4′,4′,6′,6′-Tetrachloro-2-phenoxy-l,3,7,9-tetraaza-2λ5,8λ5-diphosphatricyclo[7.3.0.03.7]dodecanspiro[8.2′]cyclotri(phosphazen)-2-sulfid (Cl4N3P3(N(CH2)3N)2P(S)OC6H5) (1) und 4,4,6,6-Tetrachloro-1,2′,4′,5′-tetramethyl-6′-phenoxycyclotri(phosphazen)-spiro[2.3′]-cyclodi(λ5-phosphadiazan)-6′-sulfid (Cl4N3P3(NCH3NCH3)2P(S)OC6H5) (2) werden beschrieben. Die Molekülstrukturen von 1 und von 4,4,6,6-Tetrachloro-l′5′-dimethyl-6′-phenoxycyclotri(phosphazen)-spiro[2.3′]-cyclodi(λ5-phosphadiazan)-6′-sulfid (Cl4N3P3(NHNCH3)2P(S)OC6H5) (3) wurden durch Röntgenstrukturanalysen an Einkristallen ermittelt und ergeben, daß die Phosphor-Hydrazin-Baueinheiten beider Verbindungen in Twistkonformationen vorliegen.
