Chemical Properties
Yellow to brown crystalline powder
Uses
Thianaphthene-3-carboxaldehyde (Benzo[
b]thiophene-3-carboxaldehyde) may be used as a starting material in the multi-step synthesis of anthra[2,3-
b:7,6-
b′]bis[1benzothiophenes (ABBTs).
It may be used in the synthesis of :
- 6-(N,N-dimethylamino)-2-(benzo[b]thiophen-3-yl)quinazolin-4-one
- 6-(pyrrolidin-1-yl)-2-(benzo[b]thiophen-3-yl)quinazolin-4-one
- (Z)-2-(benzo-[b]-thio-phen-3-yl-methyl-ene)-1-aza-bi-cyclo-[2.2.2]-octan-3-one
General Description
Thianaphthene-3-carboxaldehyde, also known as benzo[
b]thiophene-3-carboxaldehyde, can be synthesized from 3-methyl-benzo[
b]thiophene. It undergoes phosphine-free palladium coupling with aryl halides to form 2-arylbenzo[
b]thiophenes.
