Abstract: | The stereochemistry of coupling reactions of Grignard reagents and symetrical organomagnesium compounds with the silicon atom of 1,2,3,4-tetrahydro-2-(1-naphthyl)-2-silanaphthalene is studied. The results show that the electrophilic at the leaving group, by the metal atom is not a main factor for the retention of the configuration. It is possible to give a first explanaion of the stereochemical pathway of these reactions by considerig the “hard and soft” character of the attacking organometallic as well as polarisability of the leaving group. |
