-
Paragraph 0108-0113, (2021/03/30)
The invention discloses a sulfonimide photo-acid generator with high acid yield. The sulfonimide photo-acid generator has a structure as shown in a general formula (A) in the description. The acid generator has high sensitivity to active energy rays with the wavelength of 300-450nm, particularly 365nm (I rays) and 405nm (H rays), and is good in solubility and strong in acidity.

Carbazole is an important compound in pharmaceuticals and functional materials. A new Pd(II) supramolecular cage-catalyzed protocol for the synthesis of multifunctional carbazoles from indoles is described through regioselective successive oxidative Heck reactions. This new protocol is highly efficient, with a low Pd (2.4 mol%) catalyst loading and good compatibility for both N-H free and N-protected indole substrates. Moreover, it can be used to synthesize carbazoles with various functional groups by a one-pot two-step procedure. The excellent catalytic activity can be attributed to the distinct properties of the supramolecular cage structure in uniformly distributive and well-defined Pd(II) active centers on the cage surfaces.
