Deoxygenation is a chemical reaction involving the removal of oxygen atoms from a molecule (e.g. A=O → A), or the removal of molecular oxygen (O2) from a reaction mixture or solvent.

DEOXYGENATION Trimethylborane and water reduce this isotwistane xanthate ester quantitatively.
Looking for a way to tweak the reaction conditions, the researchers came across a lone report of a triethylborane-air deoxygenation of a xanthate ester that seemed to proceed via the slow reduction of an alkyl radical.
Realizing that they may have discovered a new procedure for deoxygenation, Wood's team tried the reaction with a series of xanthate esters and found that the reaction was indeed a general deoxygenation procedure.
The Barton-McCombie deoxygenation is an organic reaction in which an hydroxy functional group in an organic compound is replaced by a proton to an alkane
Main disadvantage of this reaction is the use of the tin hydride which is toxic, expensive and difficult to remove from the reaction mixture.
It is found by theoretical calculations that that a O-H homolysis reaction in the borane-water complex is endothermic with an energy similar to that of the homolysis reaction in tributyltin hydride but much lower than the homolysis reaction of pure water.
