The interaction of CO with copper oxide clusters of different size, composition, and charge is investigated infrared multiple-photon dissociation (IR-MPD) spectroscopy and density functional theory (DFT) calculations. Laser ablation of...

Here we systematically investigate the CO and H activation and dissociation on small Cu Zn (n=3-6) clusters using Density Functional Theory. We show that Cu Zn is a superatom, displaying...

P-Functional phosphanylated tetrathiafulvalenes 3a-f were synthesised stepwise lithiation and phosphanylation of TTF derivatives, and then reacted with PCl to form the related -chloro compounds 4a-f. Reactions of 4c-f with LDA...

A novel bis-CF-substituted diazaphosphole was synthesized selectively from hexafluoro-2-butyne and a 3-1,2,3,4-triazaphosphole derivative. The [4+2] cycloaddition and subsequent cycloreversion reaction under elimination of pivaloyl nitrile affords the product in high...

Anionic 1,4-dihydro-1,4-diphosphinines were synthesized from tricyclic 1,4-diphosphinines and isolated as blue powdery salts M[-]. Reaction of solutions of these monoanions with iodomethane led to -methylated compounds -. An oxidation/reduction cycle...

Activation of CO is the first step towards its reduction to more useful chemicals. Here we systematically investigate the CO activation mechanism on CuX (X is a first-row transition metal...

Synthesis of the tricyclic 1,3-dithiole-2-thione-derived 1,4-dihydro-1,4-diphosphinine is presented using a base-induced ring formation protocol and chloro(diethylamino)(1,3-dithiole-2-thion-4-yl)phosphane as the starting point. P-oxidation reactions of dihydrodiphosphinine by chalcogens led to bis(-oxide), bis(-sulfide),...

We present the stereospecific synthesis of helicenoid-based phosphepines (7-membered P-rings) as well as chiral P-containing polycyclic aromatic hydrocarbons. In these systems, an axial to central chirality transfer takes place from...

The base-induced (-BuOK) rearrangement reactions of 3,4-dihydro-2-1,2,3-benzothiadiazine 1,1-dioxides result in a ring opening along the N-N bond, followed by ring closure with the formation of new C-N bonds. The position...

A phosphanido-type bridged bis(imidazolium) salt, readily prepared in two steps via reductive deselenization of a tricyclic 1,4-diphosphinine diselone, affords access to a novel anionic P-functional tricyclic bis(NHC) via deprotonation. The...
