Dichlorocarbene addition to allyl phenyl ether under phase-transfer catalysis conditions—A kinetic study

The kinetics of dichlorocarbene addition to allyl phenyl ether have been studied under phase-transfer catalytic conditions using aqueous sodium hydroxide as the base and benzyltriethylammonium bromide as a phase-transfer catalyst. The reaction was carried out at 35 °C under pseudo-first-order conditions by keeping aqueous sodium hydroxide and chloroform in excess and was monitored by GC. The effect of various experimental parameters on the rate of the reaction has been studied and based on the results obtained, a suitable mechanism is proposed.

The kinetics of phase-transfer catalysed dichlorocarbene addition to allyl phenyl ether has been investigated under biphase condition. The apparent rate constant of this reaction was obtained from experimental data. The effects of the reaction conditions, including agitation speed, amount of chloroform, quaternary ammonium salts, temperature and the amount of sodium hydroxide were investigated in detail.Figure optionsDownload as PowerPoint slide
