Trichloroacetimidates, glycosylations, silver trifluoromethanesulfonate

Douglas, S P, Whitfield, D M, Krepinsky, J J, Silver trifluoromethanesulfonate(triflate) activation of trichloroacetimidates in glycosylation reactions, J. Carbohydr. Chem., 12, 131-136, 1993. 

In addition the selective activation of both glycosyl trichloroacetimidates (using catalytic triethylsilyl trifluoromethanesulfonate at —78 °C) and glycosyl bromides (using silver trifluoromethanesulfonate and collidine) over selenoglycosides can be achieved.
