## Abstract 2‐Hydroxythiophen exists at room temperature mainly in the tautomeric form 2(5H)‐thiophenone^13^ and is conveniently prepared^3^ by splitting 2‐thienyl __t__‐butyl ether by heating it with catalytic amounts of __p__‐toluenesulphonic acid at about 150°. 2(5H)‐Thiophenone, an α,β‐unsatura
Regioisorneric, C(5)-halogenated derivatives were also prepared by a different method. They can be readily differentiated from the C(4)-substituted series by 'H-NMR spectroscopy. Regioselectivity of the opposite direction has been predicted for 'strongly' electron-deficient olefins [ 131.
