This invention relates to high nucleation density organometallic ruthenium compounds. This invention also relates to a process for producing a high nucleation density organometallic ruthenium compound comprising reacting a bis(substituted-pentadienyl)ruthenium compound with a substituted cyclopentadiene compound under reaction conditions sufficient to produce said high nucleation density organometallic ruthenium compound. This invention further relates to a method for producing a film, coating or powder by decomposing a high nucleation density organometallic ruthenium compound precursor, thereby producing the film, coating or powder.

Overzeolite H‐ZSM‐5, the aromatics‐based hydrocarbon‐pool mechanism of methanol‐to‐olefins (MTO) reaction was studied by GC‐MS, solid‐state NMR spectroscopy, and theoretical calculations. Isotopic‐labeling experimental results demonstrated that polymethylbenzenes (MBs) are intimately correlated with the formation of olefin products in the initial stage. More importantly, three types of cyclopentenyl
通过GC-MS,固态NMR光谱和理论计算研究了H-ZSM-5沸石上甲醇到烯烃(MTO)反应的基于芳烃的烃池机理。同位素标记的实验结果表明,聚甲基苯(MBs)在初始阶段与烯烃产物的形成密切相关。更重要的是,首次通过固态NMR光谱法鉴定了三种类型的环戊烯基阳离子(1,3-二甲基环戊烯基,1,2,3-三甲基环戊烯基和1,3,4-三甲基环戊烯基阳离子)和五甲基苯甲鎓离子。在共同进料([ 13 C 6 ]苯和甲醇)条件下和典型的MTO工作(进料[ 13C]甲醇)条件。13 C标记实验显示了MBs(从二甲苯到四甲基苯)和碳阳离子(三甲基环戊烯基和五甲基苯离子)的可比反应性,证明它们通过配对机制共同作用产生丙烯。DFT理论计算也支持基于芳烃的完整催化循环中的配对路线。

Several substituted bis(cyclopentadienyl)- and bis(indenyl)methanes were synthesized directly from the corresponding cyclopentadienes (indenes) and ketones in KOH/DME two-phase mixture.

It is shown that the cyclopentadienide anion can undergo an electrophilic substitution. In methylation reactions it was possible to stop the reaction at the intermediate 5-substituted cyclopentadiene stage. In the methylcyclopentadienide anion, the methyl group directs an electrophile to the adjacent carbon atom.

Reactions of different cyclopentadienes with phorone were studied. Nonsubstituted and monosubstituted cyclopentadienes form annelation products,viz., 4,4,8,8-tetramethyl-1, 3a,4,5,6,7,8,8a-octahydroazulen-6-ones.
