| Kristall-und Molekülstruktur von 2-[3-(N,N-Diethylammonium)propylimino]-2-phenyl-dithioacetat Crystal and Molecular Structure of 2-[3-(N,N-Diethylammonium)propylimino]-2-phenyl-dithioacetate  | | | Abstract
| The title compound, formed by the reaction o f acetophenone with 3-diethylamino-1-propylamine and sulfur, crystallizes in the orthorhombic space group P 2 12 12 1 (Z = 4) with lattice constants a = 818.1(2) pm, b -1225.1(2) pm and c = 1622.4(4) pm. The characterization of the molecule as a zwitterion is established by the observed bond parameters. Both spec troscopic investigations and the results of the X-ray structure determination show that a hydrogen atom is bonded to the amino nitrogen rather than to the imino nitrogen. | | |

| 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. | | |
