Mononuclear and dinuclear palladium and nickel complexes of phosphinimine-based tridentate ligands

The tridentate bis-phosphinimine ligands O(1,2-C6H 4NPPh3)21, HN(1,2-C2H 4NPR3)2 (R = Ph 2, iPr 3), MeN(1,2-C 2H4NPPh3)24 and HN(1,2-C 6H4NPPh3)25 were prepared. Employing these ligands, monometallic Pd and Ni complexes O(1,2-C6H 4NPPh3)2PdCl26, RN(1,2-CH 2CH2NPPh3)2PdCl][Cl] (R = H 7, Me 8), [HN(1,2-CH2CH2NPiPr3)2PdCl][Cl] 9, [MeN(1,2-CH2CH2NPPh3)2PdCl] [PF6] 10, [HN(1,2-CH2CH2NPPh3) 2NiCl2] 11, [HN(1,2-CH2CH2NPR 3)2NiCl][X] (X = Cl, R = iPr 12, X = PF6, R = Ph 13, iPr 14), and [HN(1,2-C6H4NPPh3) 2Ni(MeCN)2][BF4]Cl 15 were prepared and characterized. While the ether-bis-phosphinimine ligand 1 acts in a bidentate fashion to Pd, the amine-bis-phosphinimine ligands 2-5 act in a tridentate fashion, yielding monometallic complexes of varying geometries. In contrast, initial reaction of the amine-bis-phosphinimine ligands with base followed by treatment with NiCl2(DME), afforded the amide-bridged bimetallic complexes N(1,2-CH2CH2NPR3)2Ni 2Cl3 (R = Ph 16, iPr 17) and N(1,2-C6H 4NPPh3)2Ni2Cl318. The precise nature of a number of these complexes were crystallographically characterized.

Control of Chemo-, Regio-, and Enantioselectivity in Copper Hydride Reductions of Morita-Baylis-Hillman Adducts

Nonracemically ligated copper hydride can be used to effect tandem SN2?/1,2-reductions of racemic Morita-Baylis-Hillman (MBH) acetates to access enantioenriched chiral allylic alcohols with defined olefin geometry. MBH esters, including those with beta-substitution, can be transformed to stereodefined enoates by taking advantage of a bulky, oligomeric, in situ generated trialkoxysiloxane leaving group. Finally, an atypical conversion of easily arrived at MBH alcohol derivatives to nonracemic allylic alcohols is disclosed.

Anion-exchange-triggered 1,3-Shift of an NH proton to iridium in protic N-heterocyclic carbenes: Hydrogen-bonding and Ion-pairing effects

Proton release: A series of five-coordinate iridium(l) phosphine complexes with protic N-heterocyclic carbene ligands have been prepared which display NH-Cl hydrogen bonding (see scheme; cod = 1,5-cyclooctadiene). Exchange of the chloride for less coordinating anions triggers the reversible 1,3-shift of the NH proton to the iridium, which is thought to proceed by a novel water-assisted protonrelay mechanism.

Halogen Photoelimination from Monomeric Nickel(III) Complexes Enabled by the Secondary Coordination Sphere

Endothermic halogen elimination reactions, in which molecular halogen photoproducts are generated in the absence of chemical traps, are rare. Inspired by the proclivity of mononuclear Ni(III) complexes to participate in challenging bond-forming reactions in organometallic chemistry, we targeted Ni(III) trihalide complexes as platforms to explore halogen photoelimination. A suite of Ni(III) trihalide complexes supported by bidentate phosphine ligands has been synthesized and characterized. Multinuclear NMR, EPR, and electronic absorption spectroscopies, as well as single-crystal X-ray diffraction, have been utilized to characterize this suite of complexes as distorted square pyramidal, S = 1/2 mononuclear Ni(III) complexes. All complexes participate in clean halogen photoelimination in solution and in the solid state. Evolved halogen has been characterized by mass spectrometry and quantified chemically. Energy storage via halogen elimination was established by solution-phase calorimetry measurements; in all cases, halogen elimination is substantially endothermic. Time-resolved photochemical experiments have revealed a relatively long-lived photointermediate, which we assign to be a Ni(II) complex in which the photoextruded chlorine radical interacts with a ligand-based aryl group. Computational studies suggest that the observed intermediate arises from a dissociative LMCT excited state. The participation of secondary coordination sphere interactions to suppress back-reactions is an attractive design element in the development of energy-storing halogen photoelimination involving first-row transition metal complexes.
