There is provided a composition comprising a compound represented by general formula (I), wherein R1 represents a 5-iodothiophen-2-yl group or the like, and R2 represents a 4-dimethylaminophenyl group or the like. This composition is useful for diagnosis of an amyloid-related disease such as Alzheimer's disease because the compound has high binding specificity to amyloid β protein, high permeability through the blood-brain barrier, and a property of being rapidly eliminated from sites other than senile plaques in the brain.

hybrids of thiophene and aniline, is studied utilizing experimental and theoretical methods. Synthesis of new short chain 3-(N-alkylamino)thiophenes is discussed, and a mechanism of electropolymerization is proposed whereby oxidation occurs through removal of a nitrogen lone pair electron, followed by a chemical step resulting in radical contribution at the 2-position of the thiophene ring. Coupling of
There is disclosed a process for the production of 2-thiophene aldehydes, in which the 2-thiophene aldehydes are obtained by the formylation of thiophene or deriva - tives thereof with formamides and phosgene.
