Participants

Reaction Steps

0.46 g (0.95 mmol) of methyl 4-(8,8-dimethyl-5-p-tolyl-7,8-dihydro-2-naphthylselanylethynyl)benzoate is dissolved in 20 ml of tetrahydrofuran, 2 ml of ethanol and 1 ml of water, and 0.46 g (11 mmol) of lithium hydroxide monohydrate is then added. The reaction medium is refluxed for 15 hours, acidified with 2N hydrochloric acid solution and then extracted with ethyl acetate. The solid obtained is washed with a heptane/ethyl ether mixture (90/10) and then purified by chromatography (eluent: dichloromethane). An off-white powder is obtained (0.2 g; yield=45%).
