  Synthesis, characterization and catalytic activity of rare-earth metal complexes incorporating indolyl ligands. Dalton Transactions , 44 (47), DOI: /C5DTH. The synthesis, characterization, and mesomorphic properties of a new type of heteronuclear compounds 1a c and a Pd complex 1d derived from benzoxazole as the core group are reported.

The carbohydrazide is a versatile key intermediate for the synthesis of several heterocyclic systems such as pyrazoles, thiazoles, 1,3,4-oxadiazoles, and 1,2,4-triazoles [24, 25].Hence, the carbohydrazide 4 was treated with various reagents to afford pyrazole and 1,3,4-oxadiazole derivatives (Scheme 2).Condensation reaction of carbohydrazide 4 with dicarbonyl compounds, namely, acetylacetone. A convenient synthesis of substituted Pyrazolo[1,5-a]pyrimidine was carried out by the reaction of different ketene dithioacetals with different aromatic amine in isopropanol in the presence of potassium carbonate. The newly synthesized compound were characterized by 1H NMR, IR, Mass and screened for their antimicrobial activity against various strains of bacteria and fungi.

The ligand coordinates to molybdenum(ii) as either a uni- or a bi-dentate ligand, and the reversibility of the ketone coordination is demonstrated by the interconversion of the complexes [MoCl(CO)(2)(L-kappa P-1)(eta (5)-C5H5)] 1 and [Mo(L-kappa P-2,O)(CO)(2 Cited by: InSu et al.

New 3-(2-pyrrolyl)indole systems were synthesized on the basis of heterocyclization of 3-acylindole oximes with acetylene in a superbase medium (the Trofimov reaction).

It is shown that only the anti form of the oxime participates in the formation of the pyrrole ring.

The phosphorus NMR chemical shift of 1 is with δ P = in the same range as the corresponding signals of indolyl ( ppm) and pyrrolyl ( ppm) dichlorophosphine.

The characterization of PPy nanoparticles was done by Fourier transform infrared spectrometer. Graphene was synthesized from intercalated graphite by exfoliation at $${^{\circ}}$$ C for 30 s in tube furnace, and particle size was assessed.

The synthesis and late transition metal chemistry of 7-aza-N-indolyl phosphines and the activity of their palladium complexes in CO-ethene co-polymerisation Cell extracts were used to study. A new kind of pyridine‐containing aromatic diamine monomer, 4‐phenyl‐2,6‐bis[4‐(4‐aminophenoxy)phenyl]‐pyridine (PAPP), was successfully synthesized by a modified chichibabin reaction of benzaldehyde.

The indolyl exception is caused by the distorted and thus less stable structure of the bi-indolyl borane anion. The inter-ring repulsions between hydrogen atoms next to the nitrogen atom force the two indole rings out of plane, which are missing in more nitrogen containing azolyl rings.
