Aryl C(sp²)-X Coupling (X = C, N, O, Cl) and Facile Control of N-Mono- and N,N-Diarylation of Primary Alkylamines at a Pt(IV) Center.

ABSTRACT: We present the first example of an unprecedented and fast aryl C(sp²)-X reductive elimination from a series of isolated Pt(IV) aryl complexes (Ar = p-FC₆H₄) LPt^IVF(py)(Ar)X (X = CN, Cl, 4-OC₆H₄NO₂) and LPt^IVF₂(Ar)(HX) (X = NHAlk; Alk = n-Bu, PhCH₂, cyclo-C₆H₁₁, t-Bu, cyclopropylmethyl) bearing a bulky bidentate 2-[bis(adamant-1-yl)phosphino]phenoxide ligand (L). The C(sp²)-X reductive elimination reactions of all isolated Pt(IV) complexes follow first-order kinetics and were modeled using density functional theory (DFT) calculations. When a difluoro complex LPt^IVF₂(Ar)(py) is treated with TMS-X (TMS = trime
