Facile synthesis, spectroscopic characterization, and crystal structures of dioxybiphenyl bridged cyclotriphosphazenes

2-Naphthylthio Cyclotriphosphazene Derivatives: Synthesis, Characterization, Crystallographic and Fluorescence Properties

“…The most well-known and studied derivatives of cyclophosphazenes are trimer (hexachlorocyclotriphosphazene) and tetramer (octachlorocyclotetraphosphazene). Thanks to their active phosphorus-chlorine bonds, they can be used with many different groups and easily give chlorine displacement reactions (10)(11)(12)(13)(14)(15)(16). Another reason these compounds are preferred is to be used as the starting material in the preparation of polyphosphazenes which is the largest class of known inorganic polymers (12).…”

“…Another reason these compounds are preferred is to be used as the starting material in the preparation of polyphosphazenes which is the largest class of known inorganic polymers (12). Also, they can be used as ligand in coordination chemistry and organometallic chemistry (10)(11)(12)(13)(14). Six-membered trimer (P3N3) is more preferred and studied than eight-membered tetramer (P4N4) because it is planar, stable, rigid, and its product range is less than tetramer (17)(18)(19)(20).…”

Efficient Synthesis by Mono‐Carboxy Methylation of 4,4′‐Biphenol, X‐ray Diffraction, Spectroscopic Characterization and Computational Study of the Crystal Packing of Ethyl 2‐((4′‐hydroxy‐[1,1′‐biphenyl]‐4‐yl)oxy)acetate

“…In this context, 4,4′‐Biphenol which is a colorless solid of organic nature is also an important candidate to be utilized for the production of valuable bioactive compounds acyl hydrazones with the potential application such as against influenza virus agonists and compounds having antihemolytic activity . Beside this, 4,4′‐Biphenol has enormous role in the production of important synthetic scaffolds such as brominated derivatives, di‐nitro and mono‐nitro functionalized compounds, reduced into asymmetric products, oxidized into bicyclohexyl‐2,5,2′,5′‐tetraene‐4,4′‐dione, fluorosulfuric acid 4′‐fluorosulfonyloxy‐biphenyl‐4‐yl ester, for the production of hydroxyphenyl cyclohexanones and dioxybiphenyl bridged cyclotriphosphazenes etc (See Figure ).…”
