Room‐temperature hydroamination of 1,3‐dienes with aniline [Eq. (1)] is efficiently catalyzed by cationic η 3 ‐allyl palladium complexes, prepared by treating [{( η 3 ‐allyl)PdCl} 2 ] with 1,2‐diaryl‐3,4‐bis[(2,4,6‐tri‐ tert ‐butylphenyl)phosphinidene]cyclobutenes and AgOTf in CH 2 Cl 2 ; Ar=2,4,6‐tri‐ tert ‐butylphenyl.
