Description	Partially protected D-xylofuranose, D-erithritol and D-threitol were alkylated with 2,2,3,3,4,4,5,5,6,6,7,7,7-tridecafluoroheptyl)oxirane using boron trifluoride diethyl etherate as a catalyst. The desired deoxy fluoro compounds were isolated only in low to medium yields. The fluoroalkylation was accompanied with disproportionation of the protected acetal group and by polymerization. Thus, the stability of starting compounds towards an attack of Lewis acid-type catalyst was investigated in various solvents. A mechanism explaining the action of catalyst has been proposed.
