Cationic Tetrylene‐Iron(0) Complexes: Access Points for Cooperative, Reversible Bond Activation and Open‐Shell Iron(−I) Ferrato‐Tetrylenes**

Reversible piezochromic behavior of two new cationic iridium(III) complexes.

We demonstrate that two new cationic Ir(III) complexes exhibit an interesting piezochromism, and their emission color can be smartly switched by grinding and heating. This is the first example that the Ir(III) complexes display piezochromic phosphorescence.

Regiospecific C-H bond activation: reversible H/D exchange promoted by CuI complexes with triazamacrocyclic ligands.

Selective C H bond activation by metals under mild conditions is a major subject of research targeting the final functionalization of organic substrates. The characterization of the usually unstable intermediates of the C H bond activation prior to functionalization is crucial for the mechanistic comprehension of the reaction. Different mechanisms, such as oxidative addition, electrophilic meta...

Access Control and Handover Strategy for Multiple Access Points Cooperative Communication in Vehicle Environments

Kinetic and thermodynamic preferences in aryl vs benzylic C-H bond activation with cationic Pt(II) complexes.

Anhydrous cationic Pt(II) complexes [(NN)Pt(CH3)(CF3CD2OD)]+ (1, NN = ArN=C(Me)-C(Me)=NAr), which are obtained by reaction of (NN)Pt(CH3)2 with B(C6F5)3 in CF3CD2OD, activate C-H bonds of benzene and methylbenzenes, with enhanced reactivity compared to the previously prepared equilibrium mixtures with the (thermodynamically favored) aquo complexes. For methylbenzenes (toluene, p-xylene, mesityl...

Synthesis and reversible reductive coupling of cationic, dinitrogen-derived diazoalkane complexes.

A series of cationic diazoalkane complexes [4-RC(6)H(4)C(H)NNMo(N[t-Bu]Ar)(3)][AlCl(4)], [1-R][AlCl(4)] (R = NMe(2), Me, H, Br, CN; Ar = 3,5-C(6)H(3)Me(2)) has been prepared by treatment of the N(2)-derived diazenido complex Me(3)SiNNMo(N[t-Bu]Ar)(3) with 4-RC(6)H(4)CHO and 2 equiv of AlCl(3). The structures of [1-H][AlCl(4)] and [1-NMe(2)][AlCl(4)] were determined by X-ray crystallography. The...
