Provided is a colored photosensitive curing composition useful for color filters in primary colors, including blue, green, and red, having a high molar absorption coefficient and allowing a reduction in film thickness and superior color purity and fastness.
A colored photosensitive curing composition, comprising, as its colorant, a dipyrromethene-based metal complex compound obtained from a metal or metal compound and a dipyrromethene-based compound represented by the following Formula (I):
wherein in Formula (I), R
1
to R
6
each independently represent a hydrogen atom or a substituent group; and R
7
represents a hydrogen or halogen atom, or an alkyl, aryl or heterocyclic group.
An efficient Rh(iii)-catalyzed ortho-selective C–H activation and tandem oxidative olefination-cyclization of aryl sulfonamides is described. The protocol has been applied to various substrates with good functional group tolerance.

A ruthenium-catalyzed sulfonamide-directed ortho aryl C-H alkenylation/annulation to afford five-membered sultam by using of molecular oxygen as an oxidant is reported in this article. Compared to the previous transition-metal-catalyzed C-H alkenylation of aryl sulfonamides, no excess metal salt oxidant was required in this method. A wide sulfonamide substrates scope and good regioselectivity and site-selectivity
In this Letter, triazoles as carbene reagents were used for sulfonamide-directed C-H insertion carbenoid functionalization to construct benzylpyridine sulfonamide dual-pharmacophore compounds. This method is simple and efficient and can be used for the late-stage modification of sulfonamide drugs.
