Synthesis of two novel dinuclear palladium(I) complexes and studies of their catalytic activity in amination reactions

Two novel palladium(I) dinuclear complexes have been prepared and their structural characterization has revealed an unprecedented μ2- η3:η3 coordination between a phenyl ring from PtBu2Bph (Bph = Biphenyl) and the PdI-Pd I unit present in the complexes.

Unexpected formation of a phenonium ion-containing salt by single electron-transfer oxidation of a cage compound possessing triphenylamine moieties

The phenonium ion-containing salt 6-Cl+SbCl6 - was unexpectedly generated in the tris(4-bromophenyl)aminium hexachloroantimonate-promoted, single electron-transfer oxidation reaction of 9,10-bis(4-diphenylaminophenyl)tetracyclo[6.2.0.04,10.0 5,9]decane (5). X-ray crystallographic analysis and quantum chemical calculations reveal that the cation in 6-Cl+SbCl6 - contains a unique bridging phenonium ion structure that is stabilized by the presence of a cross-conjugated N,N-diphenyldivinyliminium ion (3-diphenylamino-1,3-cyclohexadienyl cation). It is noteworthy that 6-Cl +SbCl6- is a trapped product of a phenonium like radical cation 6+, the radical cation mutant of 2+.

(DiMeIHeptCl)Pd: A Low-Load Catalyst for Solvent-Free (Melt) Amination

(DiMeIHeptCl)Pd, a hyper-branched N-aryl Pd NHC catalyst, has been shown to be efficient at performing amine arylation reactions in solvent-free ("melt") conditions. The highly lipophilic environment of the alkyl chains flanking the Pd center serves as lubricant to allow the complex to navigate through the paste-like environment of these mixtures. The protocol can be used on a multi-gram scale to make a variety of aniline derivatives, including substrates containing alcohol moieties.

Tuning the Donor-π-Acceptor Character of Arylborane-Arylamine Macrocycles

Donor-π-acceptor compounds based on arylamine and arylborane moieties connected by a π-conjugated linker are attractive materials in organic electronics and imaging applications due to the strong charge transfer character that leads to low energy absorption and solvatochromic emission properties. Here we introduce a new conjugated macrocyclic system that consists of four arylborane and two arylamine units as confirmed by single-crystal X-ray structure analysis. The acceptor character of the arylboranes is enhanced by exocyclic electron-withdrawing 2,4,6-tris(trifluoromethyl)phenyl (FMes) substituent as well as the mutual interaction between adjacent boranes. The absorption, solvent-dependent emission, and electrochemical properties are studied and compared to those of other macrocyclic organoboranes. Computational studies offer additional insights into the electronic structure. Due to the enhanced acceptor character of the boranes, the LUMO orbitals are lower lying, leading to more facile reduction, red-shifted absorption and emission, and larger Stokes shifts than those found for previously studied B-N macrocycles.

Catalytic and Aerobic Oxidative Biaryl Coupling of Anilines Using a Recyclable Heterogeneous Catalyst for Synthesis of Benzidines and Bicarbazoles

In this study, a heterogeneous rhodium-catalyzed oxidative homocoupling reaction of anilines utilizing molecular oxygen as the sole oxidant is reported. Employing a commercially available and recyclable Rh/C catalyst enabled the oxidative dimerization of various anilines, including N,N-disubstituted and N-monosubstituted anilines, as well as diarylamines, triarylamines, and carbazoles. Additionally, the catalytic protocol was extended to the ortho-ortho coupling of anilines, affording 2,2′-diaminobiphenyls with high regioselectivity. Notably, the developed approach provides rapid access to diversely functionalized benzidines and diaminobiphenyls in an operationally simple, practical, and environmentally friendly manner.

Transition-Metal-Free Diarylation of Isocyanates with Arynes
