The interaction of thiazolo(4,5- e )(1,2,4)triazines with bicyclo(2.2.1)heptadiene at a high pressure (up to 15 kbar) results in the corresponding thiazolo(4,5- b )pyridines, and this is the key step of a new approach to fused pyridines based on the tandem S N H − S N H reactions on the...
Ultrasonic aerosol spray pyrolysis was applied to obtain CaCuMn 6 O 12 bulk ceramics with a microstructure consisting of necked submicron particles demonstrating advanced functional properties due to a large contribution of intergrain tunneling magnetoresistance
The reactions of 2-chloro-4-(substituted amino)-6-methyl-5-nitropyrimidine 1 with (L)-α-amino acids gave substituted derivatives 3, which were converted to optically active imidazo(1,2- a )pyrimidines 4 by treatment with either phosphorus oxychloride or polyphosphoric acid.
Stable dimethyl (3-benzoyl-2,2,2-trimethoxy-5-phenyl-2,3-dihydro-1,2λ 5 -oxaphosphol-4-yl)phosphonate was obtained in 98% yield from the reaction between dibenzoylacetylene and 1-methylimidazole-2-thiol in the presence of trimethyl phosphite in dry diethyl ether.
Xerogels containing thiol groups (1.0–2.7 mmol g– 1 ) and having high specific surface areas of 630–970 m 2 g– 1 were obtained by the sol–gel method using a structure-forming agent (1,2-bis(triethoxysilyl)ethane or 1,4-bis(triethoxysilyl)benzene) and a functionalising agent...
The interaction of diethyl phosphite with phenylacetylene within the coordination sphere of the trialkynemonocarbonyl-molybdenum(0) complex produces diethyl (Z)-2-phenylvinylphosphonate.
The treatment of LiCH(SiMe 3 ) 2 with Bu t CN followed by the addition of m - and p -cyanopyridines gave two tert -butyl- and pyridyl-substituted β-diketiminato lithium complexes ( Li ( L ‾ L ′ ) n ) (LL’ = N(SiMe 3 )C(Bu t )C(H)C( m -Py)NSiMe 3 (1) and LL’ = = N(SiMe 3 )C(Bu t )C(H)C( p...
The energy of a strong intramolecular N–H⋯S bond (N⋯S 2.9617(5) Å) in the crystal of titled compound has been estimated and compared with energies of intramolecular N–H⋯O and O–H⋯N H-bonds.
The condensation of resorcinol or methylresorcinol with methylaminoacetaldehyde dimethyl acetal in an acid medium results in the formation of 2,2-bis((2,4-dihydroxyaryl)ethyl)methylamine hydrochlorides
The reaction of powders resulting in the excitation of uranyl ions occurs anomalously quickly for a solid-phase reaction.
