中科院福建物构所鲍红丽课题组在国家重点研发计划(2017YFA0700103)、国家自然科学基金(21672213,21871258,21922112)和中科院战略性先导科技专项(XDB20000000)等项目支持下,近期提出了一个巧妙的策略,即利用廉价的氘水作为氘源,通过极性反转策略将羰基还原氘代,以良好的收率和高的氘代率制备α-氘代醇(图二)。该体系仅需1.5当量的氘水,成本仅为现有技术的百分...
Treatment of N,N-bis(2-hydroxybenzyl)-2-(2-aminoethyl) dimethylamine (H2had) with trans-[ReO2(py)4]I in acetone affords the iodide salts of the oxypyridinium-ammonium zwitterions N1-(2-hydroxybenzyl)-...
摘要 Trimethylsilyl groups have been used in our research as a director as well as a bulky and lipophilic group in our quest for natural and non-natural molecules.

Hydrotalcite-like compounds, [Mg1−xAlx(OH)2]x+ [xX− · n H2O], where X− = ½ CO32- or OH−, were prepared by hydrothermal syntheses at PH2O = 100 MPa and T = 100°–350°C. St...
Syntheses of Glauconite at Surface Temperatures     Glauconite  Diagenesis  Pore solutions  Synthesis       font style='font-size:12px;'> 2012/2/9
Glauconite has been synthesized at low temperature by precipitation of Fe-hydroxides from Si-, Fe-, Al-, and K-containing solutions under reducing conditions. The compositions favorable for the synthe...
The basic salts of this system were prepared and their structures and physico-chemical properties were studies by electron microscopy, chemical analysis, X-ray powder diffraction, thermal analysis, i....
An attempt has been made to synthesize nitrogenous clay minerals hydrothermally from silica-alumina gels in the presence of amino acids, namely glycine and lysine. The products have been characterized...
