Synthesis of organoboron compounds

Synthesis of organoboron compounds from organomagnesium compounds 

---

The reaction is called hydroboration and is a versatile synthesis of organoboron compounds. One example is the addition of diborane, B2H6, to ethene. Di-borane behaves as though it is in equilibrium with BH3 (B2H6 <= 2BH3), and addition proceeds in three stages ... 

Scheme 4 Synthesis of organoboron compounds via transmetallation with Si or Sn compounds.

The traditional synthesis of organoboron compounds from organic halides is based on the reaction of trialkyl borates with Grignard or lithium reagents. However, the cross-coupling reaction of diboron solves the difficulties associated with the use of Mg/Li compounds. The cross-coupling reaction of diborons...

Any worker dealing with reactions mixtures containing organoboron compounds would be likely to be interested in methods for determining these substances which are intimately tied up with either the starting materials used in the synthesis of organoboron compounds or could occur as side products in the reaction mixture. 

Transition metal boryl (M-BY2, Y=OR, NR2, alkyl, etc.) complexes have attracted considerable interest because they play important roles as reactive intermediates in many catalytic processes for the synthesis of organoboron compounds which are important reagents in organic chemistry enabling many chemical transformations [1-19]. Over the past few decades, tremendous progress has been made in the aspects of their syntheses, reactivities, and structures, and a number of reviews have...
