2-Fluoromethyl-4,4,6-trimetiiyl-1,3-oxasine as a new reagent for the preparation of α-fluoroaldehydes
Patrick, Timothy B.,Hosseini, Sedigheh,Bains, Satinder
, p. 179 - 182 (1990)
The title compound easily forms an anion on treatment with n-butyllithium. The anion reacts with electrophiles such as alkyl halides, aldehydes, and ketones. The resulting products furnish α-fluoroaldehydes after reduction and hydrolysis.
