[reaction: see text] Directly mixing primary, secondary, and tertiary alcohols with nC(4)F(9)SO(2)F-NR(3)(HF)(3)-NR(3) in THF or MeCN results in convenientconversion to the corresponding fluorides in high yields. The readily available reagents are easy to handle, and the mild, almost neutral reaction conditions allow for excellent functional group compatibility. A NR(3)(HF)(3)/NR(3) ratio of

prepared from 3-O-methylated- and 3-O-benzylated glucofuranosides as well as 3-O-benzylated allofuranoside were also subjected to 1,3-dipolar cycloaddition reactions with six azidopyranosides under similar reaction conditions to generate a series of 1,5-disubstituted triazole-linked disaccharides. The synthesis of all 1,5-disubstituted triazolylated monosaccharides as well as all 1,5-disubstituted triazole

A metal-free, vinyl sulfone-based synthesis of 1,5-disubstituted-1,2,3-triazoles is reported for the first time. These triazoles are easily formed in a regioselective fashion by heating under reflux a mixture of a substituted vinyl sulfone and an organic azide ‘on water’. This powerful and practical route has the potential to be exploited for the synthesis of complex 1,5-disubstituted-1,2,3-triazoles.
