Authors report the formation and full characterization of weak adducts between Li+ and Na+ cations and a neutral iron(0) complex, [Fe(CO)3(PMe3)2] (1), supported by weakly coordinating [BArF20] anions, [1·M][BArF20] (M = Li, Na). The adducts are found to synergistically activate aliphatic C-X bonds (X = F, Cl, Br, I, OMs, OTf), leading to the formation of iron(II) organyl compounds of the type [FeR(CO)3(PMe3)2][BArF20], of which several were isolated and fully characterized. Stoichiometric reactions with the resulting iron(II) organyl compounds show that this system can be utilized for homocoupling and cross-coupling reactions and the formation of new C-E bonds (E = C, H, O, N, S). Further, they utilize [1·M][BArF20] as a catalyst in a simple hydrodehalogenation reaction under mild conditions to showcase its potential use in catalytic reactions. Finally, the mechanism of activation is probed using DFT and kinetic experiments that reveal that the alkali metal and iron(0) center cooperate to cleave C-X via a mechanism closely related to intramol. FLP activation.

Author is Barbolla, Iratxe; Sotomayor, Nuria; Lete, Esther.

A convergent route to pyrrolo[1,2-b]isoquinolines with a quaternary center at C-10 was developed, which implies a sequential Pd(0)-catalyzed carbopalladation followed by cross-coupling reaction with boronic acids. The adequate catalytic system and exptl. conditions, with and without the use of phosphine ligands, were selected to control the chemoselectivity of the process, allowing a 6-exo-carbopalladation to generate a quaternary center and avoiding a direct Suzuki coupling. A variety of electron-rich and electron-deficient arylboronic acids can be used providing an efficient route to substituted pyrrolo[1,2-b]isoquinolines in moderate to good yields (up to 94%, 22 examples).

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 1-(Bromomethyl)-2-iodobenzene, is researched, Molecular C7H6BrI, CAS is 40400-13-3, about Non-conventional synthesis and photophysical studies of platinum(II) complexes with methylene bridged 2,2′-dipyridylamine derivatives.Computed Properties of C7H6BrI.

Methylene bridged 2,2′-dipyridylamine (dpa) derivatives and their metal complexes possess outstanding properties due to their inherent structural flexibility. Synthesis of such complexes typically involves derivatization of dpa followed by coordination on metals, and may not always be very efficient. An alternative synthetic approach, involving the derivatization step after – rather than prior to – coordination of dpa on metal center, is proposed and applied to synthesis of a number of platinum(II) complexes with substituted benzyldi(2-pyridyl)amines. Comparison with the more conventional synthetic route reveals greater efficiency and versatility of the proposed approach. The obtained complexes are not luminescent in solution at room temperature, but display blue phosphorescence emission (∼415 nm) with the lifetimes of μs order in glassy matrix at 77 K, with addnl. green (∼485 nm) and relatively long living (τ = 3.7 ms) emission in the case of iodine substituted derivative
