Hemilability 意味

Web1 jul. 2014 · Hemilabile ligands are known to impart remarkable properties to their metal complexes. Herein, we present arene half-sandwich complexes of RuII, OsII, and IrIII with “click”-derived 1,2,3-triazole (L1) and 1,2,3-triazol-5-ylidene (L2) ligands containing a potentially hemilabile thioether donor. Structural elucidation of the complexes revealed … WebThis system enables near-quantitative hydrogenation of ketones, imines, aldehydes, and esters at the catalyst loadings as low as 5-200 ppm. Our analysis points to the crucial role of the phosphine hemilability for the catalyst activation step and the stability of the reactive species under the catalytic conditions.

WebHighly porous metal–organic frameworks (MOFs), which have undergone exciting developments over the past few decades, show promise for a wide range of applications. However, many studies indicate that they suffer from significant stability issues, especially with respect to their interactions with water, which severely limits their practical potential. WebWe have recently synthesized a new series of “hybrid” ortho-phosphinoaniline ligands possessing both soft phosphine and hard amine donors (Figure 1).When coordinated to late transition metals (specifically Rh and Ru) these ligands can give rise to hemilability in which the soft phosphorus terminus binds more strongly to the soft metal center, effectively …
