3-Chloro-2-methyl-1-propene → (2-methyl-prop-2-ene-1-sulfonyl)-benzene

Participants

Reaction Steps

A solution of 3-chloro-2-methyl-propene (80 ml, 0.81 mmol) in dry methanol (450 ml) was stirred at room temperature during the addition of sodium benzenesulfinate (200 g, 1.22 mmol). The resulting suspension was refluxed for 20 hours, cooled to room temperature and concentrated in vacuo. The residue was poured onto water (600 ml) and the resulting solid filtered, washed three times with water (200 ml) and dried under vacuum for two days to give (2-methyl-prop-2-ene-1-sulfonyl)-benzene (156 g, 99%) which was used in the next step without further purification.
