Abstract
In comection with the syntheses of 2-organoelement-1,3-diphospholanes and -diphosphorinanes other compounds of this type and further methods of preparation are described. These P,E,P-heterocycles are formed by interactions of alkaliphosphides, Ph(M)P-(CH2)n-P(M)Ph (n[dbnd]2,3/M[dbnd]K), or trimethylsilylphosphines, Ph(SiMe3)P-(CH2) -P(SiMe3)Ph (n[dbnd]2,3), with organoelement halides, R2ECl2 and RECl2, respectively. In some cases polymeric compounds are obtained. The reaction of ethylen-bis-phenylchlorphosphine with methylamine gives an aza-diphospholidine. The structure of the title compounds is elucidated by investigation of their mass and 31P-nmr spectra.Keywords
