INSERTION OF REACTIVE INTERMEDIATES IN TELLURIUM AND SELENIUM COMPOUNDS

Cel


This project is based on research work on compounds that contain selenium (se) and tellurium (te). In particular it is concerned with: the reactions of insertion of carbenes, dihalocarbenes, diacetylides and dinitrides in the bonds se-se and te-te of dialkyl and diarylditelluride and the corresponding compounds of selenium; and the reactions of insertion of carbenes and dihalocarbenes in the bonds tellurium-halogen (Te-X) and selenium-halogen (Se-X) of dialkyl and diaryldihalotelluride and dialkyl and diaryldihaloselenide. The first objective of the project is to synthesise and to characterise new compounds which contain two atoms of Se or of Te in their molecules. The compounds with which the project will start are the bis(aryltelluro)ethyne. Later the synthesis of the corresponding derivatives of selenium will be tackled. A second objective of the project is an understanding of the reactivity exhibited by these compounds.
So far 6 Te compounds of the form Ar-Te-C = C-Te-Ar have been synthesised. From the point of view of characterisation, work is aimed at obtaining and studying spectroscopic data. On the crystallographic side, there are problems in obtaining monocrystals of these compounds which are suitable for study by monocrystal X-ray diffraction. So far four monocrystals have been tried of which only two have been acceptable. The X-ray diffraction spectrum has been recorded and one crystal structure has been resolved.
