A Tale of Two Steps: Unraveling the Reaction Mechanism

So, how does this magic happen? Let’s embark on a two-step journey:

  1. The Spark of a Reaction: First, we’ll mix an organoborane, a molecule with a boron-hydrogen bond, with our star ingredient, mercury(II) acetate. This union sparks a reaction, creating an organomercury intermediate – a key player in our tale.
  2. Water Magic: In the second step, it’s time for some H2O action! We add water to the reaction mixture, causing the organomercury intermediate to undergo hydrolysis. This transformation releases our desired hydroxylated organic product, along with a happy little side product of mercury(0).

Regio- and Stereoselectivity: Guiding the Reaction’s Precision

This reaction is not just a random act of chemistry; it’s a dance of precision. Markovnikov’s rule steps in to guide the regioselectivity, meaning the addition of the boron atom will occur at the less substituted carbon of the double bond.

But it doesn’t stop there! Our reaction also exhibits stereoselectivity, favoring the formation of a specific stereoisomer. This means we can control the spatial arrangement of the atoms in our product, creating molecules with tailored properties.
