| Abstract: | Synthesis and NMR Spectroscopic Investigations of Dibenzo d,g]-1,3-dioxa-2-element-6-silocine Bis-(o-halogenoaroxy)silanes react with sodium via metallation and a fast two-step 1.3]-rearrangement to the sodium salts of bis(o-hydroxyaryl)silanes. These are cyclized in a one-pot-reaction with element halides of silicon, phosphorus and arsenic to the title compounds of the general formula R1R2Si(C6H4O)2E (E = SiR2, P(Y)R, As(Y)R). One conformer is prefered according to N.M.R. spectroscopical investigations. |
