Substituted arylethanols can be coupled by using a readily available Ru catalyst in a fully deoxygenative manner to produce hydrocarbon chains in one step. Control experiments indicate that the first deoxygenation occurs through an aldol condensation, whereas the second occurs through a base‐induced net decarbonylation. This double deoxygenation enables further development in the use of alcohols as
The long and the short of it: An atom‐economicalroute to α,ω‐diarylalkanes from ω‐arylalkanols was achieved by a direct one‐step method, or a sequential two‐step method depending on the alkyl chain length. The reaction proceeded through the formation of β‐methylhydroxy‐α,ω‐diarylalkanes by dehydrogenation/β‐alkylation, followed by dehydrogenation/decarbonylation.
