Abstract:
Dehydrogenation of tertiary alcohols is both highly challenging and of notable importance in synthetic chemistry. We report a readily available Co2(CO)8 catalyzed hydrosilylation protocol for the reductive deoxygenation of tertiary alcohols involving a radical mechanism. Successful deoxygenation of various tertiary, secondary and primary alcohols demonstrated the broad applicability, including syntheses of fine chemicals. A plausible mechanistic path was proposed based on several control experiments.

Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
