| Research Abstract |
Phenylazomethine dendrimers with a ruthenium porphyrin core can discriminate the shape of various guest molecules. Shape dependent catalytic conversion was studied by using this dendrimer-based nanospace. For example, the catalytic activities as TOF value for epoxidation reactions of various olefins were determined. Herein, we employed3 different structural isomers of methoxystyrene derivatives (o-, m- or p-) for the comparison. As the result, the meta-substituted substrates are relatively selected by the dendrimer catalyst, affording the corresponding m-substituted epoxide as the product. Similarly, phenylstyrene derivatives were also confirmed to exhibit similar selectivity. It is noteworthy that the experimental results are in good agreement with the expectation based on a molecular structural simulation.
