1-METHYL-2-(TRIBUTYLSTANNYL)-1H-PYRROLE Chemical Properties,Usage,Production

Uses

It is employed as intermediate for pharmaceutical.

Uses

1-Methyl-2-(tributylstannyl)pyrrole can be used as a reactant to prepare:

• Bithienylpyrrole derivatives through a Stille coupling reaction with bithienyl bromides in the presence of Pd catalyst.
• Di(bisthienyl)-o-carborane (DBTC) by reacting with 5,5′-dibromo-o-carboranyl-bisthiophenes using Pd catalyst. DBTC is electropolymerized to produce conducting polymers.
• Poly(Py-BTz-Py) (2-butyl-4,7-bis(1-methyl-1H-pyrrol-2-yl)-2H-benzo[d][1,2,3]triazole) via Stille coupling reaction. Poly(Py-BTz-Py) can be used as an organic photocatalyst for the formation C-C bond under visible light irradiation.
