Eksempler på brug af CYANO i en sætning

• The name is also used for the CN radical, and hence is used for compounds such as cyanogen bromide (NCBr) (but see also Cyano radical).
• In organic chemistry, a cyanohydrin or hydroxynitrile is a functional group found in organic compounds in which a cyano and a hydroxy group are attached to the same carbon atom.
• The cyano in the term cyanobacteria refers to its colour, not to its relation to cyanides, though cyanobacteria can catabolize hydrogen cyanide during nitrogen fixation.
• In this general Michael addition scheme, either or both of R and R' on the nucleophile (the Michael donor) represent electron-withdrawing substituents such as acyl, cyano, nitro, or sulfone groups, which make the adjacent methylene hydrogen acidic enough to form a carbanion when reacted with the base, B:.
• This is followed by ring closure via nucleophilic attack on the cyano group, after which the imidate intermediate is rearomatized.
• In order to allow efficient magnetic, metal ions should be bridged by small ligands allowing for short metal-metal contacts (such as oxo, cyano, and azido bridges).
• It is possible to use benzoyl chloride but the yields and regioselectivity of the addition of the cyano group are lower.
• In contrast, cyanoborohydride is a weaker reductant owing to the electron-withdrawing cyano substituent.
• 106 species of Macrophytes (belonging to 87 genera of 46 families), which includes 14 rare species and 208 species of Phytoplankton comprising 106 species of Chlorophyceae, 37 species of Cyano phyceae, 34 species of Euglenophyceae, 27 species of Bacilariophyceae and 4 species of Dinophyceae.
• AtzA was shown to displace fluoride as well as chlorine but not azido, cyano, methoxy, which are of similar size and electronegativity, or thiomethyl or amino groups.
• Three cyano groups of the cyanate ester are trimerized to a triazine ring structure, hence the T in the name.
• Treatment of this intermediate with 3-ethyl-N-methylaniline leads to addition to the cyano group and formation of the corresponding diaryl guanidine, aptiganel, 3.
• Treatment of that intermediate with Raney nickel reduces the cyano group to the corresponding primary amine; this product then undergoes an internal ester-amine interchange to yield the cyclized lactam (5).
• Cyano cyclotrimerization reactions occur under ionothermal conditions, where CMPs are obtained in molten zinc chloride at high temperatures.
• Radical hydrothiolation of an unsaturated functional group indirectly generates a carbon-centered radical, which can then cyclize intramolecularly onto alkenes, oxime ethers, isocyanides, cyano groups, and aromatic rings.
• This intermediate was treated with thionyl chloride and disulfur dichloride to convert the oxime to a cyano group and chlorinate the imidazole in the position next to the phenyl ring.
