-
Paragraph 0020; 0022; 0023, (2017/07/31)
PROBLEM TO BE SOLVED: To provide a method for manufacturing 1-(2-aminophenyl)-3-phenylurea with high selectivity without using a specific organic solvent or a specific reaction device with a smaller solvent amount than conventional methods. SOLUTION: Ther
RECORDING MATERIAL PRODUCED USING NON-PHENOL COMPOUND
-
Paragraph 0120, (2015/10/28)
An object of the present invention is to provide a recording material or a recording sheet using, as a color-developing agent, a non-phenol compound that is a safe compound in no danger of corresponding to an endocrine disruptor and is good in color devel
Triple-signaling mechanisms-based three-in-one multi-channel chemosensor for discriminating Cu2+, acetate and ion pair mimicking AND, NOR, INH and IMP logic functions
Singh, Prabhpreet,Singh, Harminder,Bhargava, Gaurav,Kumar, Subodh

Chemosensor 1 shows three different responses towards Cu2+, acetate and Cu(OAc)2 ion pair at different wavelengths independently in its absorption and fluorescence behaviour following a triple-signaling mechanism, namely, internal ch
Desymmetrisation of aromatic diamines and synthesis of non-symmetrical thiourea derivatives by click-mechanochemistry
Strukil, Vjekoslav,Margetic, Davor,Igrc, Marina D.,Eckert-Maksic, Mirjana,Friscic, Tomislav
supporting information, p. 9705 - 9707 (2012/10/29)
ortho- and para-Phenylenediamines were desymmetrised and quantitatively transformed into mono- and bis-(thio)ureas or mixed thiourea-ureas through a one-pot mechanochemical click reaction sequence; mechanochemical desymmetrisation proceeds quantitatively
Amide- and urea-functionalized dithienylethene: Synthesis, photochromism, and binding with halide anions
Li, Ziyong,Zhang, Chan,Ren, Yanliang,Yin, Jun,Liu, Sheng Hua
supporting information; experimental part, p. 6022 - 6025 (2011/12/15)
A versatile amide- and urea-functionalized dithienylethene has been successfully synthesized. Upon irradiation with UV or visible light, the compound showed excellent fatigue resistance. As a synthetic receptor, the dithienylethene displayed switchable af
Simple, novel synthesis for 1-carbamoyl-lH-benzotriazole and some of its analogs
Perry, Christopher John,Holding, Keith,Tyrrell, Elizabeth
, p. 3354 - 3365 (2008/12/22)
1-Carbamoyl-1H-benzotriazole (benzotriazole-1-carboxamide, 2a), an effective carbamoyl chloride substitute, and a range of its analogs can be synthesized in good yields in two very simple steps from 1,2-diaminobenzene. The facile preparation of the interm
