Abstract
3,5-Di-tert-butyl-1,2-benzoquinone (5) reacts with trialkyl phosphites (6) to give the respective penta-oxyphosphoranes 7. On the other hand, the reaction of quinone 5 with dialkyl phosphites affords the phosphonate adducts 13. Analytical and spectroscopic (1H, 31P. 19F and 13C NMR) results are in accord with the given structures. The ground state structure of pentaoxyphosphoranes 7 was also studied in the light of NMR time scale spectroscopic results.Keywords
