Because of their easy preparation and relative stability in air, the nanoparticles of coinage metals, such as copper, silver and gold, were widely reported, and there are many excellent examples on th
The development of convenient and efficient methods for the synthesis of benzothiazoles and benzimidazoles is attracting considerable attention due to their antitumor, anticancer, and antimicrobial ac
近期,关于杂核金属配合物的研究已经引起了人们的极大关注.因为杂核金属元素提供了有效的协同作用,在协同作用中,整个体系的活性大于两个单体活性的总和[1].最近的研究进展已经表明,这些配合物可以用作催化剂,光学器件,磁性材料和半导体.
钛酸酯配合物不仅在化学领域而且在生物抗癌活性方面应用广泛,所以一直以来是比较热门的研究课题[1].钛酸酯配合物不仅可以有效的催化己内酯的开环聚合[2]、Hetero-DielsAlder和醛氰缩合,还可以作为有效的存储材料和抗癌抗菌物质[3].我们课题组合成一系列含咪唑并[1,5-a]吡啶配体(L)的钛酸酯配合物,并探索了它们的抗癌抗菌性能(Scheme 1).
β-Substituted cyclohex-2-enones are widely used in Michael reactions, eycloadditions,dehydrogenation reactions, and others.1 Moreover, this motif constitutes an essential component of a variety of bio
Photocatalytic oxygen evolution (water oxidation) is the crucial step for solar water splitting.Despite significant efforts to develop inorganic semiconductor-based photocatalysts, recent progress dem
许多二烃基锡(Ⅳ)化合物由于具有较好的抗癌活性而受到人们的关注.大量的研究结果表明,二烃基锡化合物的抗癌活性受烃基的影响较大[1,2],而其它配体的结构也有一定的影响,尤其在水解、转移过程中,某些配体还可起到协同作用[3,4].
Ammonia borane (H3N-BH3, AB) is considered an ideal material for chemical hydrogen storage due to its very high H density (19.6 weight ％ H) and has attracted much research attention.1 Our approach to
N-heterocyclic carbene transition-metal complexes have exhibited remarkable success in the areas such as metathesis and coupling reactions1, and have showed enhanced catalytic activity compared to the
Nitrogen-containing heterocycles are structural constituents of many bioactive natural products, medicinally important compounds and organic materials.[1] In particular, indazoles and pyrazoles are pr
