Chemistry of Tetradentate [C,N : C,N] Iminophosphorane Palladacycles: Preparation, Reactivity and Theoretical Calculations

A theoretical and experimental study of tetradentate [C,N : C,N] iminophosphorane palladacycles was carried out for the purpose of elucidating their behavior as compared to the parent Schiff base analogues to determine the prospect of encountering new A-frame structures for the iminophosphorane derivatives. The DFT calculations were in agreement with the experimental results regarding the performance of these ligands. New insights into the chemistry of the related dinuclear species have been obtained.

A simple and effective synthesis of aryl azides via arenediazonium tosylates

Aromatic azides are formed in high yield from arenediazonium tosylates and sodium azide in water at room temperature or from aromatic amines via diazotization in the presence of p-TsOH Besides being experimentally simple, these methods do not require any metal catalysis and provide clean products without purification.

Synthesis and insecticidal activity of N,N'-bis (3-substituted thiourea) methylenedianiline derivatives

Bis thiourea derivatives (5a-e) were synthesized by the treatment of diisothiocyanate (4) with various secondary amines and anilines. The structures of the compounds (5a- e) were confirmed by their spectral analysis. The insecticidal activity of the diisothicoyanate (4) and bisthiourea derivatives (5a-e) were studied and found to be better activities in comparison with the standard drug.

New polytriazoleimides with high thermal and chemical stabilities

A series of novel polytriazoleimides were prepared from various aromatic dianhydrides and a new kind of 1,2,3-triazole-containing aromatic diamine synthesized by the Cu (I)-catalyzed 1,3-dipolar cycloaddition reaction in DMAc, and characterized by FT-IR, 1H-NMR, XRD, DSC and TGA techniques. The results show the polytriazoleimides are soluble in most of strong polar solvents and have inherent viscosity values of 0.51-0.62 dL/g(DMAc). The polytriazoleimide films exhibit a tensile strength of 62.3-104.5 MPa and an elongation at breakage of 4.0-8.1%, a glass transition temperature (Tg) of 257-275°C, a decomposition temperature (at 5% weight loss) of 350-401°C in N2 atmosphere, and a dielectric constant of 2.47-3.01 at 10 MHz, which depend on the structure of the polymers. The polytriazoleimides perform good resistance to acid and alkali solution.

Size-specific ligands for RNA hairpin loops

The targeting of one mRNA in the transcriptome requires small molecules that bind with substantial affinity and specificity. As such, compounds with specificity for individual RNA secondary structural motifs could be useful for targeting RNA. Described herein is the synthesis of a combinatorial library of 105 dimers of deoxystreptamine and the subsequent identification of compounds with specificity for specific RNA hairpin loop sizes, including tetraloops and octaloops. Such compounds will be useful for the perturbation of RNA function in vivo. Copyright
