A soluble iron(II)-phthalocyanine-catalyzed intramolecular C(sp)-H amination with alkyl azides.

Herein, we describe a soluble iron(II)-phthalocyanine, [Fe(BuPc)(py)] (Pc = phthalocyaninato(2-)), as an effective catalyst in intramolecular C(sp)-H bond amination, with alkyl azides as the nitrogen source, to afford the amination products in moderate to excellent yields with a broad substrate scope.

Fluorescence-based Polymerase Amplification for the Sensitive Detection of DNA Methyltransferase Activity.

DNA methyltransferase (MTase) is related to transcriptional repressor activity in biological functions. It is an essential for cancer diagnosis and therapeutics to detect DNA MTase activity sensitively. Here, a fluorescent system based on polymerase amplification has been developed to detect DNA adenine MTase (Dam) activity sensitively.

Application of a 2-aryl indenylphosphine ligand in the Buchwald-Hartwig cross-coupling reactions of aryl and heteroaryl chlorides under the solvent-free and aqueous conditions.

An efficient solvent-free protocol for the Buchwald-Hartwig cross-coupling reaction of aryl and heteroaryl chlorides with primary and secondary amines using the Pd(dba)/ligand 1 catalytic system has been developed. Notably, the catalytic system also efficiently catalyzed the reaction under aqueous conditions.

An active catalytic system for Suzuki-Miyaura cross-coupling reactions using low levels of palladium loading.

An easily available Pd(OAc)/(2-(anthracen-9-yl)-1H-inden-3-yl) dicyclohexylphosphine/toluene/PrOH/water catalytic system was developed, which shows high catalytic activity in the Suzuki-Miyaura cross-coupling reactions of a diverse array of aryl and heteroaryl chlorides with Pd loadings down to 0.01 mol%.
