For the first time SnCl2·2H2O has been identified as a convenient precatalyst for the synthesis of pyridine derivatives via an MCR in water. The 4-component reaction of alkyl/(hetero)aryl aldehydes, β-keto es
298K,100kPa时,用Pt作电极电解SnCl2水溶液,在阴极上析出Sn (s),其电极电势为-0.17 V。在阳极上析出O2,已知溶液 ,O2在阳极上析出的超电势为0.50 V,E?(H2O, H+?O2(g)?Pt)= 1.23 V。常数R = 8.314 J×mol-1×K-1,F = 9.65 ′ 104 C?mol-1。298 K时分解电压等于()V。精确保留至小数点后2位...
Similarity between the two hydrates in the H-bonded network is noticed but no phase transition is detected in the lower hydrate.doi:10.1016/s0167-2738(99)00167-8J PirnatZ Trontelj
