Application of 5-C5H5)Fe(CO)2(2-methylpropene)>+BF4- for the Protection of the Allyl Group in Carbohydrate Derivatives Containing O-Allyl and O-Benzyl Groups

Complex 5-C5H5)Fe(CO)2(η2-2-methylpropene)>+BF4- forms exchange complexes with the double bond in O-allyl group protected, O-benzylated sugar derivatives (6-14).From these compounds benzyl groups can be removed by catalytic hydrogenation.Decomplexation furnishes debenzylated, O-allyl groups containing products (15-22) in low to modest yields.Selective debenzylation, carbohydrates, η5-cyclopentadienyl-di(carbonyl)-η2-2-methylpropene-iron tetrafluoroborate
