Synthesis, crystallographic and spectroscopic studies of dimeric Cui complexes with Schiff-base-containing triazole ligands

New CuI complexes of the Schiff-base-containing triazole ligands N-[(E)-(4-chlorophenyl)methylidene]-4H-1,2,4-triazol-4-amine (C1Phtrz) and N-[(E)-phenylmethylidene]-4H-1,2,4-triazol-4-amine (Phtrz) have been synthesised and characterised. Depe

Multiple correlations between spin crossover and fluorescence in a dinuclear compound

Multiple correlations between spin crossover and fluorescence are established in a dinuclear compound with fluorescence from d(Fe) + π(SCN) to π*(ligand) charge transfer and correlation originated from ligand to Fe(ii) energy transfer.

Dinuclear complexes with a triple N1,N2-triazole bridge that exhibit partial spin crossover and weak antiferromagnetic interactions

The reaction of 4-phenylimino-1,2,4-triazole (1) with FeII, CoII, NiII and CuII thiocyanate produces a series of analogous dinuclear compounds of formula [M2 (1)5 (NCS)4] (2-5) as demonstrated by single-crystal X-ray diffraction studies of the FeII (2) and CoII (3) analogues. The magnetic properties of [Fe2(1)5(NCS)4]·xMeOH (x = 3.5-5) reveal a partial and gradual spin crossover (SCO) centred at TSCO = 115 K. This is confirmed by its crystal structure solved at 100, 150 and 250 K, which exhibits a gradual decrease of the Fe-N bond lengths with temperature. However, the bulk hydrated form of 2 that is generated upon exposure to air of crystals is a high-spin compound that exhibits weak antiferromagnetic interaction. The exchange coupling among the FeII S = 2 ions within the dinuclear neutral complex was evaluated as J/kB = -1.33(3) K by using the Heisenberg Hamiltonian H = -2JS1·S2. Similarly, the magnetic properties of the NiII (4) and CuII (5) analogues are dominated by moderate and weak antiferromagnetic interactions evaluated as J/kB = -13.9(3) and -0.30(5) K, respectively. The presence of strong spin-orbit coupling of the individual CoII ions impeded the evaluation of the likely antiferromagnetic interaction that leads to a singlet ground state in 3. The reported structures of 2 and 3 are new additions to a very scarce family of dinuclear complexes bearing a unique triple N1,N2-triazole bridge. Owing to its relevance in the peculiar properties of 1D triazolebased SCO materials, which are widely studied for their various potential applications, a structural analysis of this triple N1,N2-triazole bridge in reported structures of FeII and CoII trinuclear and 1D compounds is provided.

Rearrangement of N-(Alkylamino)azoles in Acid Media: A New Entry to C-Amino-N-substituted Azoles

A ring-opening / ring-closure mechanism for the thermal rearrangement of 1-(alkylamino)pyrazoles into 5-amino-1-alkylpyrazoles in acid medium has been established. 1-(Benzylamino)pyrazoles show a different reactivity, affording bis(5-amino-1-benzyl-4-pyrazolyl)phenylmethanes.The reaction was extended to 1-(alkylamino)indazoles but failed in the case of 1-(alkylamino)-1,2,4-triazoles.

Synthesis of organophosphorus compounds via silyl esters of phosphorous acids

The addition of trimethylsilyloxy phosphorus (III)derivatives generated in situ to imines at room temperature provides a mild selective and high yielding route to α-aminoalkylphosphorate and α-aminoalkylphenylphosphinate esters. Isocyanates and carbodiimides react similarly to give phosphonoureas and phosphonoguarnidines respectively aldehydes and ketones are much less reactive and cyanides are inert.

Alkylaminonitrobenzenes by Vicarious Nucleophilic Amination with 4-(Alkylamino)-1,2,4-triazoles

A series of 4-(alkylamino)-1,2,4-triazoles transfer the alkylamino group to the 4-position of nitrobenzene and various 3-substituted nitrobenzenes, with no detectable ortho substitution.By contrast 2-nitrothiophene reacts in the 3-position and 2-nitronaphthalene in the 1-position; 1-nitronaphthalene gives a mixture of products derived from dominant 2- with some 4-substitution.The orientations are discussed and rationalized.
