The structure of 2-(6'-hydroxy-2'-benzothiazolyl)-4-isopropylidene-.DELTA.2-thiazolin-5-one (4) was assigned to a byproduct formed in the chemiluminescence of esters of the dimethyl derivative of firefly luciferin. Compound 4 was chemiluminescent on reaction with potassium phenoxide and O2. Thiazolinecarboxylic acids and thiazolinones are apparently brought into equilibrium by base, and share a common intermediate in the chemiluminescence reaction.
