Herein we report on a series of bulky bis(alkyl)- and bis(silyl)- substituted polysilanes. Moreover, performed desilylation dechlorination experiments with them. These compounds were characterized by multinuclear NMR spectroscopy, mass spectrometry, X-ray crystallography. It was found that the selective formation silyl mono- di-anions is crucial for successful isolation these utilized multiple ...

Pyridazine plays a significant role in pharmaceuticals particularly in the field of medicinal chemistry. Several 4-substituted-benzylidene-6-substituted-phenyl-dihydro-pyridazin-3(2H)-one derivatives (3a-q) were synthesized and evaluated for their antimicrobial activities with an aim to obtain promising antitubercular agents. In the first step, 6-aryl-tetrahydro-pyridazin-3-ones (2) were prepar...

In this study, a class of bis-1,2-(4-aryl-2-alkyl-1H- inden-1-yl) ethane was synthesized and characterized by spectroscopic methods such as 1HNMR, 13CNMR, melting point and FTIR. bis-1,2-(4-aryl-2-alkyl-1H- inden-1-yl) ethane was synthesized by the reaction of butyl­lithium, arylindenes and dibromoethane in a facile, one-pot strategy. It’s shown that these methods have a wide scope to afford li...

A new amide substituted ligand based on 2,6-bis(pyrazol-1-yl)pyridine yields two novel Fe( ii ) complexes with very high spin crossover transition temperatures.

The reaction of [Re(H)(NO)2(PR3)2] complexes (1 a: R = PCy3; 1 b: R = PiPr3) with [H(OEt2)2][BAr(F)4] ([BAr(F)4] = tetrakis{3,5-bis(trifluoromethyl)phenyl}borate) in benzene at room temperature gave the corresponding cations [Re(NO)2(PR3)2][BAr(F)4] (2 a and 2 b). The addition of phenyldiazomethane to benzene solutions of 2 a and 2 b afforded the moderately stable cationic rhenium(I)-benzyliden...

In this article, we have obtained some novel results on bilateral generating functions of the polynomials, YYnn+rr αα−nnnn(xx;kk), a modified form of Konhauser biorthogonal polynomials, YYnn(xx; kk) by group-theoretic method. As special cases, we obtain the corresponding results on Laguerre polynomials, LLnn αα(xx). Some applications of our results are also discussed.
