Primary secondary and tertiary alcohols react with hydrogen halide (hydrochloric acid) at different rates. The driving force behind this and similar reactions is the formation of the strong PO double bond. Solventless microwave-assisted chlorodehydroxylation for the conversion of alcohols to alkyl chlorides. [8] 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.
