Most covalent organic frameworks (COFs) to date are made from relatively small aromatic subunits, which can only absorb the high-energy part of the visible spectrum. We have developed near-infrared-absorbing low bandgap COFs by incorporating donor-accepto
Polyfunctional lewis acids: Intriguing solid-state structure and selective detection and discrimination of nitroaromatic explosives

Synthesis and crystal structures of three porphyrin-based polyfunctional Lewis acids 1-3 are reported. Intermolecular HgCl...HgCl (linear and μ-type) interactions in the solid state of the peripherally ArHgCl-decorated compound 3 lead to a fascinating 3D supramolecular architecture. Compound 3 shows a selective fluorescence quenching response to picric acid and discriminates other nitroaromatic-based explosives. For the first time, an electron-deficient polyfunctional Lewis acid is shown to be useful for the selective detection and discrimination of nitroaromatic explosives. The Stern-Volmer quenching constant and detection limits of compound 3 for picric acid are the best among the reported small-molecular receptors for nitroaromatic explosives. The electronic structure, Lewis acidity, and selective sensing characteristics of 3 are well corroborated by DFT calculations.

A compound, or a pharmaceutically acceptable salt or ester thereof, having a structure of formula (I), wherein R1 is a substituted aryl or an optionally-substituted heteroaryl, provided that the heteroaryl is not pyridyl or azaborine; and each
Synthesis of aryl trimethylstannanes from aryl amines: A sandmeyer-type stannylation reaction
Qiu, Di,Meng, He,Jin, Liang,Wang, Shuai,Tang, Shengbo,Wang, Xi,Mo, Fanyang,Zhang, Yan,Wang, Jianbo

Sandmeyer-type stannylation: Stille coupling is one of the most powerful coupling reactions for C-C bond formation, whereas there are only limited methods to access aryl stannane compounds. A mild stannylation process based on a Sandmeyer-type transformation using aromatic amines as the starting materials is described. DCE: 1,2-dichloroethane. Copyright

A Sn-phony in B! BN isosteres of biphenyl compounds are prepared through Rh-catalyzed cross-coupling between 2-chloro-1,2-azaborines and arylstannanes (see scheme). The synthetic method should enable investigations of structure-activity relationships (SAR
Synthesis of estradiol backbone mimics via the Stille reaction using copper(II) oxide as co-reagent
