Resumen

A detailed DFT-level mechanism elucidation of the two-step reaction of tosylhydrazones with alkyllithium reagents (the Shapiro reaction) is presented. A rationale of the experimental regioselectivity is offered together with some suggestions for modifying the experimental main regioisomer. Also, the proposed general mechanism was checked with a recent modification of the Shapiro reaction involving a fluorination reaction. © 2015 The Royal Society of Chemistry.
