The present invention relates to a cobalt-nitrosyl complex having photocleavable ligands. The cobalt-nitrosyl complex provided in one aspect of the present invention is adept in the delivery of NO, with exquisite temporal control using light, without gene editing. In addition, the complex provided in one aspect of the present invention is excellent in biocompatibility because it is chemically stable, non-toxic at cell level, and non-perturbative in cellular environments.
A Cu<sup>I</sup>/Cu<sup>III</sup> prototypical organometallic mechanism for the deactivation of an active pincer-like Cu<sup>I</sup> catalyst in Ullmann-type couplings
Unraveling the mechanistic details of copper-catalyzedarylation of nucleophiles (Ullmann-type couplings) is a very challenging task. It is a matter of intense debate whether it is a radical-based or an organometallic redox-based process. The ancillary ligand choice in Ullmann-type couplings plays a key role in such transformations and can strongly influence the catalytic efficiency as well as the
阐明亲核试剂的铜催化芳基化(Ullmann型偶联)的机理细节是一项非常具有挑战性的任务。无论是基于自由基的方法还是基于有机金属氧化还原的方法,都引起了激烈的争论。乌尔曼型偶联中辅助配体的选择在此类转化中起关键作用,并且可以强烈影响催化效率及其机理。在这里,我们展示了预先设计的三齿钳状催化剂如何通过Cu I / Cu III原型机制经历失活途径,如氦标记红外光解离(IRPD)光谱法和DFT研究所证明的那样,为存在一种芳基铜III 使用该三齿配体的Ullmann偶联中的其他物种。
