The reaction of [Pd{dmba}(μ-N3)]2 (dmba = N,N-dimethylbenzylamine) with 1-(2-fluorophenyl)-3-(4-nitrophenyl)triazenido (L1) or 1,3-bis(4-nitrophenyl)triazenido (L2) anions, in methanol, and subsequent treatment with pyridine (py) allows the preparation of the corresponding cyclopalladated compounds [Pd(dmba)(L1)(py)] (1) and [Pd(dmba)(L2)(py)]·py (2). The acentric mononuclear entities of (1) and (2) are connected by weak intermolecular non-classical CH?C hydrogen bonds, which results in 2-D arrangements by translation, along the [1 0 0] and [0 0 1] crystallographic directions, respectively.

(Figure Presented) A novel type of chemodosimeters has been developed on the basis of a displacement reaction. N-Acyl-triazenes are found to be highly selective and tunable chemodosimeters toward cyanide. When N-acetyl-triazene 1a was titrated with variou

Introduced are 1,3-diaza-2-azoniaallene salts R1 - N = N+ = N - R2 X- (6) representing a new functional group. The reactive intermediates 6 are prepared by reaction of N-chlorotriazenes R1 - N = N - NCl - R2 (8) with Lewis acids. The salt 6a is stable below -50°C. It shows a strong IR band at 2018 cm-1, equivalent aryl groups in the 1H and 13C NMR spectra, and gives a correct elemental analysis. The allenes 6 undergo [4π + 2π] cycloadditions to both electron-rich and electron-deficient olefins affording 4,5-dihydro-1,2,3-triazolium salts 11 ('1,3-dipolar cycloadditions with inverse electron demand'). The cycloadditions proceed with complete conservation of the stereochemistry of the olefins. Cycloadducts 11w, 11ai of dibutyl maleate rearrange in solution into the respective more stable trans-isomers 11v, 11ah. The structure of 11m was determined by X-ray structural analysis.
