摘要:通过[rh(l)(pp *)] A类型的手性铑(i)配合物(l = Cod,[(z,Z)-Cycloocta-1,5-Diene]或nbd(norborna-2; 5-二烯),Pp * =手性bisphosphane形成7元螯合环,A =阴离子等bf 4-)往往与所造成的催化剂的部分遮挡的诱导期相关联.nbd配合物的氢化速度快于相应的cod配合物.cod / Nbd混合物的催化加氢和米氏常数的确定表明,Cod配合物在氢下的稳态浓度高于nbd配合物.但是,在氩气下,Nbd配合物占主导地位,因为与cod配合物相比,Nbd配合物具有更高的热力学稳定性.31 P-NMR谱.通过uv / Vis光谱法证明了在氢化条件下,热力学确定的cod与nbd配合物浓度之比的完全逆转.

摘要:A solid phase synthetic method for making substituted 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one. The method is useful for synthesis of large numbers of compounds through automated parallel synthesis or combinatorial library generation and is thus important to rapid discovery or new therapeutic agents containing the base structure of 1,5-benzodiazepine-2-one or 1,5-benzothiazepine-2-one.

权利人:UNIV MARYLAND
摘要:A method of room temperature synthesis of magnetic metal oxide nanoclusters within a diblock copolymer matrix includes the step of synthesizing, by ring opening metathesis polymerization technique, a diblock copolymer having a repeat unit ratio m/n, introducing, at room temperature, one or several metal containing precursors into the one block of the diblock copolymer, and processing the metal containing diblock copolymer by wet chemical technique to form nanoclusters of the metal(s) oxide within the diblock copolymer matrix. Specific reaction for synthesis of CoFe 3 O 4 and Co 3 O 4 nanoclusters within diblock copolymers, such as [NOR] m /[NORCOOH] n and [NOR] m /[CO(bTAN)] n , respectively is used in the method of the present invention.

摘要:A process is provided for the preparation of 1-amino-3-halo-4,6-dinitrobenzene and related compounds by monoamination of dihalodinitrobenzenes by ammonia in the presence of solvent and water. Using glycol as a solvent for the dihalodinitrobenzene and feeding ammonia at a rate at which it is consumed allows for the synthesis of high purity product, such as 1-amino-3-chloro-4,6-dinitrobenzene, at high yields.
