Compound: Nickel(II) chloride ethylene glycol dimethyl ether complex, is researched, Molecular C4H10Cl2NiO2, CAS is 29046-78-4, about Regioselective Alkylative Cross-Coupling of Remote Unactivated C(sp3)-H Bonds. Author is Thullen, Scott M.; Treacy, Sean M.; Rovis, Tomislav.

The functionalization of unactivated C(sp3)-H bonds poses a significant challenge due to their ubiquity and relative similarity in most organic frameworks. Herein, we describe the use of a combined photoredox and nickel catalytic system for the regioselective C(sp3)-C(sp3) coupling of unactivated C(sp3)-H bonds and alkyl bromides. Positional selectivity is dictated by a 1,5-hydrogen atom transfer (HAT) reaction by a pendent amide. Interception of this radical by a Ni catalyst allows distal alkylation to occur in good yield and excellent selectivity.

A highly chemo- and regioselective intermol. 1,2-aryl-aminoalkylation of alkenes by photoredox/nickel dual catalysis is described here. This three-component conjunctive cross-coupling is highlighted by its first application of primary alkyl radicals, which were not compatible in previous reports. The readily prepared α-silyl amines could be transferred to α-amino radicals by photo-induced single electron transfer step. The radical addition/cross-coupling cascade reaction proceeds under mild, base-free and redox-neutral conditions with good functional group tolerance, and importantly, provides an efficient and concise method for the synthesis of structurally valuable α-aryl substituted γ-amino acid derivatives motifs.

Author is Pann, Johann; Ehrmann, Katharina; Pehn, Richard; Roithmeyer, Helena; Viertl, Wolfgang; Kopacka, Holger; Brueggeller, Peter; Oberhauser, Werner.

New chelating α-aminophosphanes were obtained by Mannich-type reactions between formaldehyde, bis(2-methoxyphenyl)phosphine and aliphatic primary diamines bearing either a C2 or C3 carbon bridge between the amine functionalities. The reaction conditions, and in particular, the reaction sequence was found to significantly depend on the length of the carbon bridge of the diamine. Both obtained α-aminophosphines (i.e. N,N,N’,N’-tetra(di-ortho-anisylphosphanylmethyl)-1,2-diaminoethane (L1) and N,N,N’,N’-tetra(di-ortho-anisylphosphanylmethyl)-1,3-diaminopropane (L2)) gave along with neocuproine cationic dinuclear Cu(I) complexes. The Cu(I) complex with L2 as ligand was further converted by the aid of NiCl2(DME) (DME = 1,2-dimethoxyethane) into a tetranuclear copper cluster showing a new type of CuCl-tetramer mol. structure. All synthesized compounds were characterized in solution by multinuclear NMR-, UV/Vis-spectroscopy, mass spectrometry and in the solid state by elemental anal. and some of them by single crystal structure anal.
