antiMarkovnikovin
antiMarkovnikovin is not a term that corresponds to a widely recognized chemical substance or defined concept in established chemistry literature. In formal use, “anti-Markovnikov” describes regioselectivity in certain additions to alkenes that favor the less substituted carbon. If encountered, antiMarkovnikovin would likely be a speculative or informal label proposed to denote a hypothetical reagent, catalyst, or mechanism intended to enforce anti-Markovnikov outcomes. However, there is no standard definition or consensus around such a term.
In practical terms, anti-Markovnikov selectivity is achieved through well-known reaction pathways. For example, the radical addition
If the term antiMarkovnikovin appears in text, it should be accompanied by a clear definition specifying what
