The simple fluorinated precursor, copper(II) trifluoroacetate, Cu(CF3COO)2 can be effectively utilised in the synthesis of copper(I) nitride, Cu3N, powders and films by combinations of wet processing and gas–solid (ammonolysis) techniques. The resulting materials were characterized by powder X-ray diffraction (PXD), scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (E...

A novel polyethoxysilsesquiazane ([EtOSi(NH)1.5]n, EtOSZ) was synthesized by ammonolysis at -78 °C of ethoxytrichlorosilane (EtOSiCl₃), which was isolated by distillation as a reaction product of SiCl₄ and EtOH. Attenuated total reflection-infra red (ATR-IR), 13C-, and 29Si-nuclear magnetic resonance (NMR) spectroscopic analyses of the ammonolysis product resulted in the detection of Si-NH-Si l...

The oxidative ammonolysis route was used to synthesize three uranium nitrides, UN2, U2N3, and UN, using UF4 as the starting material. Powder XRD analysis showed the UN2 and U2N3 products to contain less than 1.0 wt % uranium oxides. UO2 level was identified to be 5.0 (0) wt % in the UN product as it is made, but this level increases upon exposure to air. The morphology of these nitrides was stu...

The title compound, C(13)H(23)N(3)O(4), was prepared starting from ethyl N-benzyl-3-oxopiperidine-4-carboxyl-ate through a nine-step reaction, including hydrogenation, Boc (tert-butoxy-carbon-yl) protection, methyl-ation, oximation, hydrolysis, esterification and ammonolysis. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds to form a porous three-dimension...

A first synthesis of a new class of novel cytosine thioglycoside analogs from readily available starting materials has been described. The key step of this protocol is the formation of sodium pyrimidine-4-thiolate via condensation of N'-arylidene-2-cyanoacetohydrazides with sodium cyanocarbonimidodithioate salt, followed by coupling with halo sugars to give the corresponding cytosine thioglycos...

A novel AIE poly(phosphoramidate) was synthesized through an ester ammonolysis reaction by using triethyl phosphate and diamines. Surprisingly, the obtained polymer is sensitive to Cu 2+ can be used as in situ visual detection agent for .

Reaction conditions, temperature and pressure ranges, for various chemical recycling proc‐ esses of polyesters are sketched in Figure 1. So far, various recycling processes for polyesters have been investigated and developed, as reviewed by Paszun and Spychaj [1]: alcoholysis with methanol or ethanol, glycolysis with ethylene glycol or propylene glycol, alkali hydrolysis with sodium hydroxide, ...

The co-ammonolysis of V(NMe2)4 and Si(NHMe)4 with ammonia in THF and in the presence of ammonium triflate ([NH4][CF3SO3]) leads to the formation of monolithic gels. Pyrolysing these gels produces mesoporous composite materials containing nanocrystalline VN and amorphous silicon imidonitride. Elemental mapping indicated a thorough distribution of VN with no evidence of large cluster segregation....
