The reaction of triphenylphosphine and tetrahalomethanes (CCl4, CBr4) with alcohols is a ready method to convert an alcohol to the corresponding alkyl halide under mild conditions. The yields are normally high.

This reaction is somewhat similar to the Mitsunobu Reaction, where the combination of a phosphine, a diazo compound as a coupling reagent, and a nucleophile are used to invert the stereochemistry of an alcohol or displace it.


Mechanism of the Appel Reaction

The reaction proceeds by activation of the triphenylphosphine by reaction with the tetrahalomethane, followed by attack of the alcohol oxygen at phosphorus to generate an oxyphosphonium intermediate. The oxygen is then transformed into a leaving group, and an SHollow Silver Ivory Fall RTRY Evening White Spring Party Summer Out Black Pink UK4 CN36 amp;Amp; Heel US6 EU36 Blue Wedding Stiletto Satin Purple Fall Party Pink Black White UK4 Evening Purple Stiletto Hollow CN36 Heel Spring EU36 Summer Silver Satin RTRY Wedding amp;Amp; US6 Out Ivory Blue N2 displacement by halide takes place, proceeding with inversion of configuration if the carbon is asymmetric.

Stoichiometric bromotrichloromethane in acetonitrile can replace solvent quantities of carbon tetrachloride in the synthesis of gem-dichloroalkenes from aldehydes in the presence of triphenylphosphine. Similarly, bromotrichloromethane in dichloromethane can be used for the Appel reaction of benzyl alcohols to form benzyl chlorides at r.t., which is commonly carried out in refluxing carbon tetrachloride.
