There has been a recent surge of interest in the use of transition metal polypyridyl complexes as visible light-absorbing photocatalysts for synthetic applications. Among the most attractive features of this approach is the availability of many known complexes with well-characterized photophysical and electrochemical properties. In particular, Ru(bpz)3 (2+) is a powerful photooxidant that has proven to be uniquely suited for oxidatively induced photoredox transformations. We present here a straightforward and high-yielding route to Ru(bpz)3(PF6)2 that features an improved Pd-catalyzed synthesis of the 2,2'-bipyrazine ligand that is amenable to gram-scale preparations.
最近，人们对过渡金属多吡啶配合物作为可见光吸收光催化剂在合成中的应用产生了浓厚的兴趣。这种方法最吸引人的特点之一是有许多具有良好光物理和电化学性质的已知配合物。特别是，Ru(bpz)3(2+)是一种强大的光氧化剂，已被证明特别适合于氧化诱导的光还原转化。我们在这里提出了一种简便高产的 Ru(bpz)3(PF6)2 路线，其特点是改进了 2,2'-联吡啶配体的 Pd 催化合成，该配体适用于克级制备。
