Controlling Oxidative Addition and Reductive Elimination at Tin(I) via Hemi‐Lability
نویسندگان
چکیده
We report on the synthesis of a distannyne supported by pincer ligand bearing pendant amine donors that is capable reversibly activating E-H bonds at one or both tin centres through dissociation hemi-labile N-Sn donor/acceptor interactions. This chemistry can be exploited to sequentially (and reversibly) assemble mixed-valence chains atoms type ArSn{Sn(Ar)H}nSnAr (n=1, 2). The experimentally observed (decreasing) propensity towards chain growth with increasing length rationalized thermodynamically and kinetically electron- withdrawing properties -Sn(Ar)H- backbone units generated via oxidative addition.

Uranium-mediated oxidative addition and reductive elimination.
Oxidative addition, and its reverse reaction reductive elimination, constitute two key reactions that underpin organometallic chemistry and catalysis. Although these reactions have been known for decades in main group and transition metal systems, they are exceptionally rare or unknown for the f-block. However, in recent years much progress has been made. In this Perspective article, advances i...

Ab initio calculations (Hartree-Fock, generalized valence bond, and configuration interaction), utilizing relativistic core potentials, have been used to follow the oxidative addition of Hz to Pt(PH,),. We find an activation barrier of 2.3 kcal/mol and an exothermicity of 15.9 kcal/mol. From examination of the geometries and wave functions, we find that up to the transition state the H-H bond i...
متن کاملPhotoinitiated Oxidative Addition of CF3I to Gold(I) and Facile Aryl-CF3 Reductive Elimination
Herein we report the mechanism of oxidative addition of CF3I to Au(I), and remarkably fast Caryl-CF3 bond reductive elimination from Au(III) cations. CF3I undergoes a fast, formal oxidative addition to R3PAuR' (R = Cy, R' = 3,5-F2-C6H4, 4-F-C6H4, C6H5, 4-Me-C6H4, 4-MeO-C6H4, Me; R = Ph, R' = 4-F-C6H4, 4-Me-C6H4). When R' = aryl, complexes of the type R3PAu(aryl)(CF3)I can be isolated and charac...
متن کاملThermodynamic control of oxidative addition and reductive elimination processes in cis-bis(dimethoxyboryl)-bis(tricyclohexylphosphine)platinum(II).
cis-[(Cy3P)2Pt{B(OMe)2}2] (1) was obtained in quantitative yield and fully characterised. The thermal stability of 1 was investigated in solution using multinuclear NMR spectroscopy revealing a hitherto unknown temperature-dependent equilibrium between 1 and the corresponding starting materials [Pt(PCy3)2] and free B2(OMe)4.
متن کاملPhotochemical Reductive Elimination of TetrachloroiodateQII)
In analogy to transition metal complexes, coordination compounds of the main group metals can be also classified according to the electron configuration at the metal. Generally, the main group metals occur in oxidation states with so, s2, s2p2 and s2p4 ground states. Recently, we studied the photolysis of so and s2 systems [l-4]. We now report the first results on the photochemistry of an s2p2 ...
