WebIn fact, it has been shown that compound 9 in contrast to related compounds forms chains via N–H⋯S hydrogen bonding. The tautomerism of 2,5-dimercapto-1,3,4-thiadiazole 34 was also examined using FTIR and FT-Raman spectroscopy, high-vacuum thermolysis experiments, as well as arylating reactions <1995JST51, 1996SPL477, 1995CJC1258, … Tautomers are structural isomers (constitutional isomers) of chemical compounds that readily interconvert. The chemical reaction interconverting the two is called tautomerization. This conversion commonly results from the relocation of a hydrogen atom within the compound. The phenomenon of … Ver mais Tautomerization is pervasive in organic chemistry. It is typically associated with polar molecules and ions containing functional groups that are at least weakly acidic. Most common tautomers exist in pairs, which means … Ver mais Valence tautomerism is a type of tautomerism in which single and/or double bonds are rapidly formed and ruptured, without migration of atoms or groups. It is distinct from … Ver mais The existence of multiple possible tautomers for individual chemical substances can lead to confusion. For example, samples of 2-pyridone and 2-hydroxypyridine do not exist as separate isolatable materials: the two tautomeric forms are … Ver mais Prototropy is the most common form of tautomerism and refers to the relocation of a hydrogen atom.
