| 概要 |
Heterogeneous catalysts composed of a vitamin B_<12> derivative with a polymer or mesoporous silica were synthesized and characterized. These two types of catalysts were used in alkane oxidation react...ions with mCPBA oxidant, and improved catalytic efficiency was obtained using the polymer supported B_<12> catalyst with a monolith structure compared to that of the monomeric B_<12> catalyst. The catalytic effects were also evaluated in several alkane substrates and the polymer supported B_<12> catalyst showed a better performance in all reactions compared to the silica-supported B_<12> catalyst.続きを見る
