Description

Application

2-Thienylmagnesium bromide is a Grignard reagent that can be used as a reactant to synthesize:

• 1-(2-thienyl)-carbinols by condensation reaction with aldehydes. Carbinols are further dehydrated to form 2-thienyl olefins.
• Thiophene-functionalized polystyrene macromonomer (ThPStM), which is employed as a key intermediate to synthesize polystyrene-graft-polythiophene (PSt-g-PTh) via a combination of atom transfer radical polymerization (ATRP) and Grignard reaction.
• Thienylene oligomers, which are used as conducting polymers and as potential OLEDs.
