A general approach to the direct deoxygenative transformation of primary, secondary, and tertiary alcohols has been developed. It proceeds through phosphoranyl radical intermediates generated by the addition of exogenous iodine radical to trivalent alkoxylphosphanes. Since these alkoxylphosphanes are readily in situ obtained from alcohols and commercially available, inexpensive chlorodiphenylphosphine
