本文通过氨基的配位作用将三联吡啶铂(Ⅱ)配合物[Pt(L)Cl]Cl固载到SBA-15分子筛的表面,利用SBA-15负载催化剂完成了可见光(λ〉400nm)催化1,4-二氢-3,5-二甲酸乙酯-2,4,6-三甲基吡啶的芳香化反应.芳香化反应产物单一,并在反应体系中检测到了氢气的生成.反应结束后,只需简单的过滤即可实现催化剂的回收利用.
Platinum(Ⅱ) terpyridyl complex incorporated into the channels of SBA-15 has been used as a photocatalyst for aromatization of 1,4-dihydro-3,5-diethyl dicarboxylates-2,4,6- trimethylpyridine. Upon irradiation, the photochemical aromatization takes place without additional oxidant, accompanied by the hydrogen production. The immobilized catalyst can be simply recycled by filtration.
