Trifluorides R2NSF3 (I; R = Me, Et, Me2CH; or R2N = pyrrolidino) were prepared by the reaction of R2NSiMe3 with SF4 in FCCl3 at -78°; I reacted with R21NSiMe3 to give R2NSF2NR21 (II; R, R1 = Me, Et; or R12 = piperidino). I and II were used to fluorinate alcs., aldehydes, or ketones. E.g., I (R = Et) reacted with Me2CHCH2OH in diglyme at -50 to -78° to give 49% Me2CHCH2F and 21% Me3CF. EtCHO with I (R = Et) in FCCl3 at 25° gave 80% EtCHF2. Among ∼23 other compounds fluorinated were: cyclooctanol, BzH, 1-naphthaldehyde, and menthol.
