Bouscasse, L. published the artcileComparison of experimental results obtained for Δ4-thiazoline-2-thiones and their 2-methylthiothiazole isomers with the values calculated by the PPP [Pariser-Parr-Pople] method, Related Products of thiazole, the publication is Bulletin de la Societe Chimique de France (1972), 1055-62, database is CAplus.
The 5-Me groups of 2-(methylthio)thiazole (I) increases the rate of quaternization by MeI, while the behavior of the Me group in II is just the opposite. The rate of formation of thiazolium iodides (III) from the 4-thiazoline-2-thiones (IV) is increased by the introduction of a 4-Me or 5-Me group. The positions of the uv absorption bands are in agreement with calculated electronic transition energies for I-IV.
Bulletin de la Societe Chimique de France published new progress about 5053-24-7. 5053-24-7 belongs to thiazole, auxiliary class Thiazole,sulfides, name is 2-(Methylthio)thiazole, and the molecular formula is C4H5NS2, Related Products of thiazole.
