Thiophenol → HCID 67900867, compound

Participants

Reaction Steps

A mixture of thiophenol (0.7 g, 6.36 millimole), ethyl 2-chloro-3-methyl-3-butenoate (1.05 g, 6.5 millimole), tetrahydrofuran (2 ml), and tetrabutyl ammonium bromide (50 mg) was stirred at room temperature while one equivalent (1.5 ml) of 4N NaOH was added rapidly. Stirring of the resulting two-phase system was continued for two hours (at room temperature). The reaction mixture was diluted with 50 ml of water and extracted twice with 20 ml proportions of ether. Evaporation of the ether left 1.4 g of a crude yellow oil. Flash column chromatography on silica gel gave the desired product, ethyl 2-thiophenyl-3-methyl-2-butenoate in 66% overall yield. The identity of the product was confirmed by proton NMR, carbon 13 NMR, and mass spectrum analysis.
