On the other hand, in the presence of 1.1 equiv of NaH in THF, the same reaction affords the corresponding E-diastereomer also with total diastereoselectivity.关键词: CATALYZED HYDROSELENATION 1ST EXAMPLE ACETYLENES DOI: 10.1021/jo0402576 被引量: 24 ...
Next, Sandmeyer reaction of thieno- pyrimidine 29 proceeded well at 70 °C in the presence of t-BuONO and C uCl2. THF/CH3CN was used as solvents to carry out maximum conversion. Later on, reaction of chlo- ride 30 with hydrazine monohydrate and furan 31 afforded required thieno...
The reaction of copper(I) complex 1 and O2 in an acetone‐containing solvent at –110 °C gave end‐on copper(II) superoxide complex 3 together with putative side‐on copper(III) peroxide complex 4, as was evident from detailed studies by variable‐temperature UV/Vis, resonance Raman, and...
As soon as the monoµ1er was completely dissolved or well dispersed in the solution, a small amount of 0.1 M FeC13 (aq) was injected into the stirred solution and the oxidative polymerization reaction was allowed to proceed for 4 h. Once FeC13 was added, the color of the reaction ...

Interestingly, although the reaction of [PtCl2(CH3CN)2] with ammonia has been known for more than a hundred years [32], the true nature of the product, [Pt(NH3)2(HNC(NH2)CH3)2]Cl2·H2O (HNC(NH2)CH3 is acetamidine) was revealed only in the 1960s by the X-ray structure analysis...
摘要: Characterization and evidence for alkylation of hydridodicarbonylcyclopentadienylrhenate(1-) ion [CpRe(CO)2H-] in the conversion of dihydrodicarbonylcyclopentadienylrhenium [CpRe(CO)2H2] to CpRe(CO)2R2. Synthesis of a rhenacyclopentane and its thermolysis to methylcyclopropane - ResearchGate...
which substances are present. Mostly, new substances are formed when more than a substance interacts with another one. There are some chemical reactions (such as decomposition) that need only one substance to react. In these cases, some triggers for the reaction...
