Rhodium-Catalyzed [2 + 2] Cycloaddition of Ynamides with Nitroalkenes

In the presence of a diene-ligated rhodium complex, ynamides and nitroalkenes undergo catalytic [2 + 2] cycloadditions to provide cyclobutenamides. The presence of sodium tetraphenylborate was found to be crucial for the reactions to proceed efficiently.
