实验步骤: Into a 100 mL round bottom flask equipped with a magnetic stirrer and reflux condenser were placed 16.0 g (0.1 mol) methyl octyl sulfide (obtained from the Aldrich Chemical Co.), 19.9 g (0.1 mol) phenacyl bromide, 25.87 g (0.1 mol) sodium hexafluoroantimonate and 40 mL acetone. The reaction mixture was brought to reflux and held at this temperature for 15 minutes. The mixture was filtered through a plug of glass wool (to remove the sodium bromide which was formed during the reaction) and the solvent was removed on a rotary evaporator, leaving 43.1 g (83.6% yield) of the desired methyl octylphenacylsulfonium hexafluoroantimonate as a tan colored solid. The product was further purified by recrystallization, first from a 1:3 mixture of water and ethanol, then, isopropanol. The pure, colorless, crystalline initiator had a melting point of 75-76° C. The initiator was soluble in a wide variety of common solvents such as acetone, methyl ethyl ketone, chloroform and methylene chloride. Into a 100 mL round bottom flask equipped with a magnetic stirrer reflux condenser obtained from the Aldrich Chemical Co to reflux The mixture was filtered through a plug of glass wool ( to remove the sodium bromide which was formed during the reaction) and the solvent was removed on a rotary evaporator

实验步骤: In a 0.3 liter stainless steel stirred autoclave, 37.9 g (0.26 mole) of n-oct-1-yl mercaptan and 20.3 g (0.29 mole) of potassium methylate were dissolved in 120 ml (3.0 moles) of methanol at 20° C., the resulting potassium octane-1-thiolate solution was heated from 20° to 150° C. in the course of 20 minutes under a carbon monoxide pressure of 300 bar, and the mixture was then kept at this temperature for 15 hours. The carbon monoxide consumed during the reaction was replaced continuously, and the pressure was kept constant at 300 bar. The mixture which emerged from the reactor was distilled under atmospheric pressure, and a methanol/methyl formate mixture was separated off and 38.2 g (92% of theory) of n-octyl methyl sulfide was obtained at 110° C./34 mbar. The carbon monoxide consumed during the reaction was distilled under atmospheric pressure a methanol/methyl formate mixture was separated off

实验步骤: The procedure of Example 1 was repeated using dimethyldisulphide (96 mg; 1.02 mmol) and 1-octene (358 mg; 3.19 mmol) in acetonitrile (15 ml) at +1.20 V until 2 coulomb equivalents of charge had been passed. After the addition of water and extraction with diethyl ether, there was obtained 106 mg of methylthio-octane. Mass Spec. m/e 217 (M+) and 44 (100%). I.R. 3300 and 1650 cm-1. of charge
