Hydrocarbon-soluble and highly reactive [(L)_xCa(CH₂SiMe₃)₂] (2a, L = tetrahydropyran, x = 4; 2b,L = tmeda, x = 2) are synthesized by the metathesis reaction of Me₃SiCH₂CaI (1-I) with KCH₂SiMe₃. The stability of 2a in tetrahydropyran solution at 0¡ã is sufficiently high for subsequent chem. transformations. The reaction of ICH₂SiMe₃ with calcium in di-Et ether yields unique iodide-bridged cage compound [Ca₃(¦Ì₃-I)(¦Ì-I)₃(¦Ì₃-OEt)(CH₂SiMe₃)(OEt₂)₅] (3). We demonstrate that alkylcalcium complexes are valuable reagents for calcium-iodine exchange reactions at C_sp2-I functionalities.

Pietrasiak, Ewa published the artcileSynthesis and characterization of fluorinated hypervalent tellurium derivatives, Category: catalysis-chemistry, the publication is Organometallics (2017), 36(19), 3750-3757, database is CAplus.

Aryl telluroethers o-substituted with acetal, aldehyde, ketone, carboxylate or aldimine donor atom functions were prepared and examined for hypervalent Te-heteroatom binding by x-ray crystallog. and tellurium-125 NMR spectra. The synthesis of tellurium derivatives bearing fluorinated groups, similar in structure to their hypervalent iodine congeners, is reported. Thus, a series of CF₃, CF₂H, and C₆F₅ aryltellurium(II) species bearing various functional groups interacting with the Te atom was obtained. The installation of the various fluorinated groups relies on the use of the corresponding trimethylsilyl precursors. The hypervalent nature of the products is discussed on the basis of their NMR spectroscopic and X-ray crystallog. characterization.

D. functional theory calculations were performed to investigate the mechanism and origins of the NHC-controlled selectivity of Ni-catalyzed C-H activation of arenes with vinylsilanes. The key to the selectivity is the different impacts of NHCs on the C-Si/C-C reductive elimination of the square-planar/T-shaped intermediate.

Arylxenon fluorides undergo substitution reactions to give sym. and asym. diarylxenons. The mols. Ar^FXeF (Ar^F = C₆F₅, 2,4,6-C₆H₂F₃) with a more polar Xe-F bond than XeF₂ are versatile starting materials for substitution reactions. Reaction of C₆F₅XeF (1) with Ar^F₂Cd gave C₆F₅XeAr^F (2, 4), which, in case of Ar^F = 2,4,6-C₆H₂F₃, upon symmetrization gave (2,4,6-C₆H₂F₃)₂Xe (5), the same result was obtained by reaction of 1 with C₆F₅SiF₃. Applying C₆F₅BF₂, with a higher F^–-affinity than the corresponding aryltrifluorosilane, in contrast gave the salt [C₆F₅Xe][Ar^FBF₃]. Using the alkenyl and alkyl compounds CF₂:CFSiMe₃/[F]^–, CF₃SiMe₃/[F]^–, and Cd(CF₃)₂ in reactions with C₆F₅XeF, the perfluoroalkenyl or -alkyl transfer reagents were consumed without formation of corresponding xenon derivatives The formation of Xe(C₆F₅)₂ in these reactions suggests the symmetrization of the corresponding vinylxenon intermediate; the unstable aryl-trifluoromethyl xenon afforded octafluorotoluene as coupling product.

Athavan, Gayathri published the artcileDirect Evidence for Competitive C-H Activation by a Well-Defined Silver XPhos Complex in Palladium-Catalyzed C-H Functionalization, Application In Synthesis of 1206-46-8, the publication is Organometallics, database is CAplus.

Increasing evidence indicates that Ag salts can play a role in the C-H activation step of Pd-catalyzed C-H functionalization. Here the authors isolate a Ag(I) complex by C-H bond activation and demonstrate its catalytic competence for C-H functionalization. Ag carbonate, a common but highly insoluble additive, reacts with pentafluorobenzene in the presence of a bulky phosphine, XPhos, to form the C-H bond activation product Ag(C₆F₅)(XPhos). By isolating and fully characterizing this complex and the related carbonate and iodide complexes, [Ag(XPhos)]₂(¦Ì-¦Ê²,¦Ê²-CO₃) and [AgI(XPhos)]₂, well-defined Ag(I) complexes can operate in conjunction with Pd complexes to achieve C-H functionalization even at ambient temperature Reactions are tested against the standard cross-coupling of C₆F₅H with 4-iodotoluene, catalyzed by Pd acetate at 60¡ã in the presence of Ag carbonate and Xphos. Key observations are that (a) PdIPh(XPhos) reacts stoichiometrically with Ag(C₆F₅)(XPhos) to form Ph-C₆F₅ instantly at room temperature; (b) catalytic cross coupling can be achieved using 5% Ag(C₆F₅)(XPhos) as the sole Ag source; and (c) Pd acetate (typical precatalyst) can be replaced for catalytic cross coupling by the expected oxidative addition compound PdIPh(XPhos). These studies lead to a catalytic cycle in which Ag(I) plays the C-H bond activation role and Pd plays the coupling role. Also, the phosphine can be exchanged between Ag complexes, ensuring that it is recycled even though Ag carbonate is consumed during catalytic cross-coupling.
