Bis(fluoromesityl) palladium complexes, archetypes of steric crowding and axial protection by ortho effect - Evidence for dissociative substitution processes - Observation of 19F-19F through-space couplings

Bisarylated complexes trans-[Pd(Fmes)2(SR2) 2](SR2)2] [Fmes = 2,4,6-tris(trifluoromethyl) phenyl (fluoromesityl); SR2 = SMe2, tht; tht = tetrahydrothiophene] are precursors for various bisarylated fluoromesityl palladium(II) complexes by ligand-substitution reactions. Boiling under reflux in acetonitrile gives the mixed complexes trans-[Pd(Fmes)2(NCMe) (SR2)], whereas boiling under reflux in toluene leads to trans-[PdCl2L2] (L = PMe3, tBuNC, pTol-NC, 4-MePy), in the presence of neutral monodentate ligands, or to (NnBu 4)[trans-Pd(Fmes)2I(SR2)] when treated with (NnBu4)I. trans-[Pd(Fmes)2(SMe2)2] reacts with bidentate ligands, also boiling under reflux in toluene, to give [Pd(Fmes)2(L-L)] [L-L = Me2bipy, 2,2′-biquinolyl, κ2N,N′-OCPy2, dppe (Ph2PCH 2CH2PPh2), pte (PhSCH2CH 2SPh), κ2S,N-SPPh2Py, κ2O,N-OPPhPy2], or the bimetallic complex [Pd(Fmes)2(μ-1κN:1,2κO:2κN-Py 2MeCO)Pd(Fmes)(SMe2)] (characterized by X-ray diffractometry) when treated with (OH)(CH3)CPy2. The crowding associated with two Fmes groups produces several interesting features: (1) trans complexes are preferred over cis complexes, against the expected electronic preferences; (2) the low-temperature NMR spectra of several complexes, or the X-ray diffraction structure of Pd(Fmes)2(2, 2′-biquinolyl)], reveal significant structural distortions associated with steric crowding; (3) the need for boiling under reflux in the synthesis suggests a dissociative substitution mechanism, which is unknown so far for Pd; (4) some of the complexes show 19F-19F through-space couplings.
