Golden frustration: The facile activation of terminal alkynes with a frustrated Lewis pair (1 and 1,4-diazabicyclo[2.2.2]octane (DABCO)) enables the development of an efficient boroauration reaction. This process can be achieved directly from alkynes, a hydroborane, [PPh3AuCl], and an organic base. ArF=2,4,6-tris(trifluoromethyl)phenyl.
