The chemistry of heterocyclic compounds has traditionally been and remains a bright area chemical science in Russia. This is due to the fact that many heterocycles find widest application. These are key structural fragments most drugs, plant protection agents. Many natural also derivatives heterocycles. At present, more than half hundreds millions known collective review devoted achievements Russian chemists this field over last 15–20 years. presents leading heterocyclists representing both...
Abstract Eight‐membered cyclic functional bisphosphines, namely 1,5‐di‐aryl‐3,7‐di(2‐pyridyl)‐1,5‐diaza‐3,7‐diphosphacyclooctanes (aryl=2‐pyridyl, m ‐tolyl, p diphenylmethyl, benzyl, ( R )‐(+)‐(α‐methyl)benzyl), with 2‐pyridyl substituents on the phosphorus atoms have been synthesized by condensation of 2‐pyridylphosphine, formaldehyde, and corresponding primary amine.

It shown that can exist in crystalline phases different parameters unit cell, which were detected PXRD data analyses. solvent-free display rare solid-state white emission room temperature, is observed due to presence broad bands...
A series of amido Ca and Yb(II) complexes LM[N(SiMe3)2](THF) (1Yb, 1-4Ca) coordinated by amidine-amidopyridinate ligands L1-4 were synthesized via a transamination reaction between proligands L1-4H bisamido M[N(SiMe3)2]2(THF)2 (M = Yb, Ca). The reactions Yb[N(SiMe3)2]2(THF)2 with L2H-L4H containing CF3 C6H4F fragments do not allow for preparing the target complexes, while analogues in good yields. Complexes 1Yb 1-4Ca evaluated as precatalysts hydrophosphination styrene, p-substituted...
Herein we report the synthesis of a stimuli-responsive binuclear Au(I) complex based on 1,5-bis(p-tolyl)-3,7-bis(pyridine-2-yl)-1,5-diaza-3,7-diphosphacyclooctane ligand, which is novel template for design luminescent metal complexes. In solid state, obtained gives three different crystalline phases, were characterized by XRD analysis. It was also found that phases can be reversibly interconverted recrystallization or solvent vapour treatment. The emission these varies in 500–535 nm range....
For the first time, 3(X + M)LCT origin of both lowest excited triplet states dual-emissive tetranuclear copper(I)-iodide complexes with octahedral Cu4I4 core has been revealed using quantum chemical computations in contrast to conventional assignment lowest-energy emission 3CC state. The unusual thermochromic behavior shown for dual from these clusters stabilized by P,N-ligands allows optical ratiometric thermal sensing a broad temperature range.
