Antipyrine derivatives I (Z = O, S; Z1 = CH2, CH2OCH2; n = 0, 1, 2, 3) were prepared as open-chain crown ether analogs. Thus, refluxing diethylene glycol ditosylate with 4-hydroxyantipyrine and K2CO3 in acetone for 15 h gave I (Z = O, Z1 = CH2OCH2). The activities of I as phase-transfer catalyst for iodination of 1-bromoctane with NaI, or KI were reported. 相似文献

肉桂醛缩(2,4-二甲基苯胺)三羰基铁(1)与苯基锂和对氯苯基锂在低温下反应,所生成的加合物继后Et3OBF4在CH2Cl2中于-60℃烷基化, 分别生成两个组成为C19H22N(CO)3FeC6H5(2)和C19H22N(CO)3FeC6H4Cl(3)的新奇的铁内盐配合物. 2晶体属单斜晶系, 空间群为P21/n, 晶胞参数为: α=10.624(3), b=25.155(6),c=19.375(9)A, β=101.13(3)°, V=5042.2A^3, Z=8, Dc=1.27g/cm^3. 2的结构用直接法解出, 并用矩阵最小二乘法修正后得最后偏离因子R为0.071. 相似文献
