POLYMERIC BENZYLTRIETHYLAMMONIUM DICHLOROIODATE AND DIBROMOIODATE - PREPARATION AND USE AS SYNTHETIC REAGENTS

Solid phase polymeric analogue of benzyltriethylammonium dichloroiodat e and dibromoiodate reagents have been prepared and used as recyclable reagents for synthetic transformations on some organic substrates. Th e development of these reagents involve polymer analogous conversions starting from crosslinked polystyrene resin. The polymeric polyhalides have been used for the addition reactions of olefins under mild condi tions. These reagents are found to undergo addition according to Marko wnikoff's rule in good yields. The spent dichloroiodate and dibromoiod ate reagents after the synthetic reactions are easily removed by filtr ation and can be recycled and reutilized.
