General description

Boron trifluoride-methanol complex (BF-M) is Lewis acid boron trifluoride incoordination with methanol. BF-M is a powerful acidic catalyst for the esterification of fatty acids. In the deacetylation of acetanilides, the complex displayed excellent deprotection selectivity against amino-protecting groups.

Application

Boron trifluoride-methanol complex is used:
  • As a reagent for deprotection of N-acetyl derivatives (acetylated amines of cyanine-type dyes).
  • As a starting material in the automated radiosynthesis procedure for [18F]tetrafluoroborate.
