 Title    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.
