If the phenyl derivative 34 was obtained in good yield (90%), the products with polar substituents were isolated only in poor yields (6% for 35 and 19% for 36). A similar effect was observed in the reactions run with azide 10, as the phenyl click product 37 was isolated in high yield (79%), while the reactions with more polar ethynyl compounds were less performant affording compounds 38 and 39 only in 26 and, respectively, 9% yield.
