Manganese‐Catalyzed Dual‐Deoxygenative Coupling of Primary Alcohols with 2‐Arylethanols

Abstract Reported herein is a general and efficient dual‐deoxygenative coupling of primary alcohols with 2‐arylethanols catalyzed by a well‐defined Mn/PNP pincer complex. This reaction is the first example of the catalytic dual‐deoxygenation of alcohols using a non‐noble‐metal catalyst. Both deoxygenative homocoupling of 2‐arylethanols (17 examples) and their deoxygenative cross‐coupling with other primary alcohols (20 examples) proceeded smoothly to form the corresponding alkenes by a dehydrogenation and deformylation reaction sequence.
