✦ Synopsis

Benzyl halides are readily carbonylated to arylacetic acids in a two-phase system (aqueous sodium hydroxide (IM), tetrabutylanraonium sulfate ; organic phase (CH2C12 or C6H6 or C6H5CH3)), using a catalytic amount of the cheap, easy to handle iron pentacarbonyl under carbon monoxide atmosphere. Transition metal carbonyl-induced carbonylation of organic halides (reaction (I)) is of considerable interest in synthesis' : RX -

In a two-phase system (saturated aqueous caLGum hydroxide, tetrab-utyZanunonium sulfate, dichZoromethane, iron pentacarbonyl) benzy2 bromides are readily carbonylated to dibenzyZ ketones ; c1-~1' dibromoortkoxylene yields the o-q&no&methane iron tricarbony2 complex 8. It 7:s inferred that the reacti
