The first known lithiated 1-azafulvene derivatives were generated by low-temperature halogen/metal interchange, with r-BuLi, from the corresponding brominated 6-diisopropylamino compounds 3b and 12. These Li species reacted with sundry electrophilic reagents to give products which, on basic hydrolys

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.
