ORGANIC SYNTHESIS USING ORGANOSULFUR-NITRITES AND -NITRATES

Thionitrites or thionitrates have been considered to be unstable.However, bulky groups' thio-NOn such as t-butylthio-nitrites and -nitrates have been readily synthesized and found to be stable enough for the use of the useful organic syntheses as an excellent nitrosation and diazotization reagents under mild conditions.Direct conversion of amines to the corresponding halides in the presence of copper halides (II), fluorination of heterocyclic amines in the presence of sodium tetrafluoroborate, α- oximation of methylene groups in ketones, facile cleavage of C=N bond to ketones, and desulfurization of thioacetals and thioketals, and other useful organic syntheses are described.

FACILE DIRECT α-OXIMATION OF KETONES USING t-BUTYL THIONITRATE

Various ketones containing methylene groups at α-position were found to react with t-butyl thionitrate at 0 deg C in tetrahydrofuran to give the corresponding α-oximino-ketones in excellent yield.
