Solventless microwave-assisted chlorodehydroxylation for the conversion of alcohols to alkyl chlorides.  The reaction is somewhat similar to the Mitsunobu Reaction, where the combination of an organophosphine as an oxide acceptor, an azo compound as a hydrogen acceptor reagent, and a nucleophile are used to convert alcohols to esters and other applications like this.

In today’s post we show that treating alcohols with HCl, HBr, or HI (which all fall under the catch-all term “HX” where X is a halide) results in the formation of alkyl halides. Peter D. Vu, Andrew J. Boydston, Christopher W. Bielawski. Keith E. Johnson, Richard M. Pagni, John Bartmess. The Appel reaction is an organic reaction that converts an alcohol into an alkyl chloride using triphenylphosphine and carbon tetrachloride. Kuang-Yu Hou, Abdul Rehman, and Xiangqun Zeng .  The corresponding alkyl bromide can also be synthesised by addition of lithium bromide as a source of bromide ions. from the ACS website, either in whole or in part, in either machine-readable form or any other form Treating a primary or secondary alcohol with thionyl chloride and pyridine generates an alkyl chloride.
