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.
Methylation of secondary amines was achieved using dimethyl carbonate or diethyl carbonate as the C1 source under the catalysis of well-defined half-sandwich iron complexes bearing an N-heterocyclic carbene ligand. The reaction proceeded under mild conditions in the presence of hydrosilanes as the reductants, and the amines were obtained with good to excellent isolated yields.
Compounds are provided that act as potent antagonists of the CCR2 or CCR9 receptor. Animal testing demonstrates that these compounds are useful for treating inflammation, a hallmark disease for CCR2 and CCR9. The compounds are generally aryl sulfonamide derivatives and are useful in pharmaceutical compositions, methods for the treatment of CCR2-mediated diseases, CCR9-mediated diseases, as controls in assays for the identification of CCR2 antagonists, and as controls in assays for the identification of CCR9 antagonists.

amides into value-added amine products is a desirable but challenging transformation. Molecules containing iminodibenzyl motifs are prevalent in pharmaceutical molecules and functional materials. Here we established a combined KOH/BEt3 catalyst for deaminative hydroboration of acyl-iminodibenzyl derivatives, including nonheterocyclic carboxamides, to the corresponding amines. This novel transition-metal-free
酰胺选择性催化C–N键裂解为增值胺产品是一种理想的但具有挑战性的转化。含有亚氨基二苄基基序的分子普遍存在于药物分子和功能材料中。在这里,我们建立了一种组合的KOH / BEt 3催化剂,用于将酰基-亚氨基二苄基衍生物(包括非杂环羧酰胺)进行脱氨基硼氢化成相应的胺。这种新颖的无过渡金属的方法也被用于氯米帕明和发光体的构建。

Developing green, efficient, and low-cost catalysts for methylation of N–H by using CO2 as the C1 resource is highly desired yet remains a significant challenge. Herein, N-doped porous carbons (NPCs) were designed, synthesized, and proved to be an excellent metal-freecatalyst for CO2-participated methylation conversion. NPCs were prepared via the pyrolysis of a mixture of tannic acid and urea. Both
