Gas-phase ring-chain tautomeric equilibria with eight 2-phenyl-substituted perhydro-l,3-oxazines and six 2-arylsubstituted 1,2-dihydro-4H-3,l-benzoxazines were studied by recording their mass spectra under different conditions. Their fragmentation behaviour was also studied using metastable ion anal
