The tautomerism between hydroxy Schiff bases, X-C6H4CR=NCMe2CH2OH (R=H, Me, C6H5; X is a range of substituents) and X-C6H4,CR=NC6H4 (o-CH2OH), and the corresponding ring closed systems, oxazolidines and dihydrobenzoxazines, has been investigated. In

The rates of cyclisation of 2-hydroxy-2-methyl-5-arylpent-4-yn-3-ones in trifluoroacetic acid are reported. An approximate ρ value of –4.0 (using σ+) and a kinetic isotope effect, KTFA/KTFA – d, of 4.2 are observed, which suggest that the react
