3% trichloroacetic acid in dichloromethane) followed by coupling of a ribonucleoside phosphoramidite in the presence of an activating reagent
Catalytic C-H functionalization is the most attractive approach to achieve this goal, as it does not require stoichiometric amounts of activating reagent
Activation was carried out in a muffle furnace, using orthophosphoric acid as activating reagent
100g of each portion of purified carbon sample was contacted with 400ml of one molar solution of each activating reagent at 200[degrees]C with stirring for two hours.
The surface pH ranged from acidic to basic depending on the activating reagent used.
