Catalytic Alkyne Arylation Using Traceless Directing Groups.

Abstract: By using Pd0/Mandyphos, we achieved a three‐component aminoarylation of alkynes to generate enamines, which are then hydrolyzed to either α‐arylphenones or α,α‐diarylketones. This Pd‐catalyzed method overcomes established known pathways to enable the use of amines as traceless directing groups for C−C bond formation. [ABSTRACT FROM AUTHOR]
