A selective and general route to (E)‐1,3‐diaryl‐prop‐1‐enes and (E)‐3‐arylallyl acetates has been developed by palladium‐catalyzed Heck‐type reactions of allylic esters with arylboronicacids or potassium aryltrifluoroborates. The present method selectively proceeds including β‐OAc elimination or β‐H elimination on the basis of the boronic acids. Whereas a variety of allylic esters were reacted with

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)
