Synthesis of New Thiazoles from α-Halohetaryl Ketones

Reactions of α-bromoacetylphenoxathiin, α-bromoacetylphenoxathiin 10,10-dioxide, or α-bromoacetylthianthrene with certain p-(arylsulfonyl)thiobenzamides lead to the formation of the corresponding 2,4-disubstituted thiazoles. The new compounds were characterized through elemental analysis and spectral data (IR, 1H NMR, and 13C NMR).
