Methyl trifluoromethane

To [Co(en)2((S)-GluOBzl)]I2 (5.0 g, 7.3 X 10 3 mol) in dry trimethyl-phosphate (18 ml, 4A sieves) contained in a conical flask equipped with a drying tube was added methyl trifluoromethane sulfonate (8.0 g, 4.9 x 10 2 mol) and the mixture was stirred at room temperature for 30 min (Caution The alkylating agent is believed to be extremely toxic. Use a hood and avoid skin and vapor contact). The deep orange solution was then slowly poured into rapidly stirred dry ether (600 ml) and the precipitated semisolid recovered by decantation. The residue was dissolved in the minimum volume of dry methanol (10-20 ml), the product reprecipitated using further dry ether (400 ml), and the solid recovered as before. A further precipitation using methanol (10-20 ml) and dry ether (800 ml) produced the complex as a finely divided solid. This was recovered by filtration (porosity 4 sin-... 

The iV-l-(4,4-dimethyl-2,6-dioxocyclohexylidene)ethyl linker has also been introduced between the C2-amino group of the glucosamine and a solid-support [5]. This linker was stable during glycosylation with thioglycoside in the presence of methyl trifluoromethane sulfonate, but readily cleaved by hydrazine, primary amines, or even ammonia.
