Fosfato-ésteres cíclicos diastereoisoméricos: 5-bromo-4-fenil-2-fenoxi-2-oxo-1,3,2-dioxafosforinanos, precursores de radicales libres alquilo β-fosfatoxi y generadores de radicales catiónicos en medio no oxidativo.

Two novel six member ring cyclic phosphates were successfully obtained. Both compound showed to be suitable β-(phosphatoxy)alkyl radicals precursors (by Tin method). Such free radicals precursors did generate radical cations in non-oxidative conditions followed by C4-C5 bond cleavage of the heterocyclic ring. In one case both contraction reaction and scrambling phosphate group were observed. In other case only the normal reduction product was observed.
