IVThe monosubstituted acetylenes H—C≡C—COOCH3 and H—C≡C—CF3 react with 1,1,3,3-tetrakis(dimethylamino)-1λ5,3λ5-diphosphete 1 to give 1,1,3,3-tetrakis (dimethylamino)- 4-methoxycarboxylato-1λ5,3λ5-diphosphorine 3, and -4-trifluoromethyl-1λ5,3λ5-diphosphorine 5, respectively. In contrast, phenylacetylene and 1 form two isomers, namely 1,1,3,3- tetrakis(dimethyl-amino)-4-phenyl-1λ5,3λ5-diphosphorine 4a und -5-phenyl-1λ5,3λ5-diphosphorine 4b. The reaction between acetylene and 1 yields the 1,1,3,3-tetrakis(dimethylamino)-1λ5,3λ5-diphosphorine 6, unsubstituted at the carbon atoms of the ring. Various mechanisms are discussed for the formation of the compounds 3, 4a, 4b, 5 and 6. All new compounds are characterized by their n.m.r., mass, and i.r. spectra.

Im Gegensatz dazu bildet Phenylacetylen mit 1 zwei Isomere, nämlich 1,1,3,3- Tetrakis(dimethylamino)-4-phenyl-1λ5,3λ5-diphosphorin 4a und -5-phenyl-1λ5,3λ5-diphosphorin 4b. Acetylen und 1 reagieren zu dem an den Kohlenstoffatomen des Rings unsubstituierten 1,1,3,3-Tetrakis(dimethylamino)-1λ5,3λ5-diphosphorin 6. Für die Bildung der Verbindungen 3, 4a, 4b, 5 und 6 werden verschiedene Mechanismen diskutiert. Alle neuen Verbindungen sind durch ihre NMR-, Massen- und IR-Spektren charakterisiert.
