Disubstituted A2-1 ,2,4-oxadiazoline-5-thiones are prepared by the reaction of N-substituted amidoximes with thiophosgene. Rearrangement, catalysed by either light or metallic copper, yields the corresponding 3,4-disu bstituted A2-I ,2,4-thiadiazolin-5-ones. Preparative Studies.-We have previously
The syntheses and mass spectra of 5,6-tetramethylenetetrahydro-l,3-oxazine-2thione and its 4-mono-and 4,4-disubstituted analogs are reported. The primary decay processes under electron impact are loss of the 1,3-oxazine ring, formation of hydrocarbon ions, and rearrangement of the [M -C6H9] + ion.
