| Reacting Zeise's salt with the phospha(III)azene (R3C)(R3Si)N-P = N-CR3 (R = CH3) (1) one gets the platinum phospha(III)azene complex (2), Cl2PtI<2 (L = 1). 2 adds water and methanol to the P=N bond of the phospha(III)azene ligand with formation of 3, Cl2Pt(PRR2 1)2 (R = (CH3)3SiO, R 1 = (CH3)3CNH) and 4, Cl2Pt(PRR 1 R 2)2 (R = CH30, R 1 = (CH3)3CNH, R2 = (CH3)3SiNC(CH3)3). 2, 3 and 4 have trans configuration, 4 also forms a mixture of the meso and d, 1 isomers. For 2 a P-a coordination of the phospha(III)-azene ligand is proposed. Die inzwischen in größerer Anzahl bekanntge-wordenen Phospha(III)azene des Typs A [la] /Py -W X N-A I | | | |

| Synthese und Additionsreaktionen von 1.3.2A 2 .4-Diazaphosphoniaahiminatacyclobutanen [1] Synthesis and Addition Reactions of l,3,2/. 2 ,4-Diazaphosphoniaaluminatacyclobutanes [1] | | | | Abstract
| -silylated aminoiminophosphines react with aluminium trihalides to give acyclic zwitterions having two-coordinated phosphorus. At about room temperature these adducts decompose by elimination of silylhalide and formation of l,3,2A 2 ,4-diazaphosphonia-aluminatacyclobutanes. Reaction of halogens and alkyl halides with the cyclic zwitterions results in formation of the corresponding 1,1-addition products. With alkyl-azides one obtains bicyclic phosphorus nitrogen heterocycles whilst in the reaction with trimethyl-silylazide the isomeric monocyclic azide derivative is formed. The IR and NMR spectra of the cyclic zwitterions are briefly discussed. | | | |
