compound 2 were studied for the oxidative catalytic conversion of olefins (cis-cyclooctene, cyclohexene and styrene) with aqueous H2O2 as oxidant. Using alcohols as solvents, 2 was employed in a one-pot two-stage strategy for converting olefins to alkoxy products, which involves oxidation (with H2O2) and acid chemistry. Mechanistic studies were carried out using different intermediates as substrates,
大环空洞素葫芦[6]尿素(CB [6])与and水配合物[MoO 2 Cl 2(H 2 O)2 ]在盐酸溶液中反应,制得水不溶性超分子化合物,其总体组成为2 [MoO] 2 Cl 2(H 2 O)2 ]·CB [6]· x H 2 O· y HCl· z(CH 3 COCH 3)(2)。单晶X射线衍射(XRD)分析表明存在桶形超分子实体CB [6]·10(H 2O)},排列成相对于相邻层偏移的层,以形成砖状图案。CB [6] /水与氢键合的实体进一步参与与水,HCl和[MoO 2 Cl 2(H 2 O)2 ]分子的分子间相互作用,从而形成三维(3D)骨架。通过热重分析(TGA),IR和拉曼振动光谱法以及13 C 1 H} CP MAS NMR对化合物2进行表征。参考络合物[MoO 2 Cl 2(H 2 O)2 ]·(二甘醇二甲醚)2(1)和化合物2以H 2 O 2为氧化剂,研究了烯烃
