Reactions of a Palladium(I) Amido Complex with Organic Halides

Le résumé fourni par la source

Structurally well‐defined mononuclear Pd(I) complexes are exceedingly rare and their reactivity remains poorly understood. Herein, the reactivity of the Pd(I) amido complex [(BINAP)Pd(NHAr Trip )] ( 1 , BINAP = 2,2′‐bis(diphenylphosphino)‐1,1′‐binaphthalene, Ar Trip = 2,6‐bis(2′,4′,6′‐triisopropylphenyl)phenyl) toward organic halides has been investigated. Complex 1 reacts with benzyl bromides in single‐electron redox reaction mechanism to furnish the Pd(II) amido complex [(BINAP)Pd(Br)(NHAr Trip )] ( 2 ) along with benzyl radical, whereas its reactions with aryl and alkyl iodides result in PdN bond cleavage, generating the aminyl radical [NHArTrip]• and Pd(0) species that subsequently performs oxidative addition reactions with organic iodides to yield organo‐Pd(II) species.
