Reaction information

*#Reaction file
reactionscheme_24 .cdx
*Reaction file type CDX
*Procedure In a 50 mL rbf a solution of Trimethyl(2-(4-(2-(4-(methylthio)phenyl)ethynyl)phenyl)ethynyl)silane (96 mg, 0.30 mmol) in 15 mL of (2/1) MeOH/DCM was stirred for 1.5 h, at r.t., in presence of K2CO3 (415 mg, 3.00 mmol, 10.00 eq.). The disappearance of starting material (Rf 0.16, (10/1) hexane/DCM) was monitored by TLC. The reaction mixture was diluted with water and extracted twice with DCM; the solution was dried over MgSO4 and evaporated to afford the pure product (74 mg, 0.30 mmol, yield 99%; Rf 0.12 in (10/1) hexane/DCM).
*Yield (%) 99 %
*Type of Yield Isolated pure product
