Direct molecular editing of heteroarene carbon–hydrogen (C–H) bonds through consecutive selective C–H functionalization has the potential to grant rapid access into diverse chemical spaces, which is a valuable but often challenging venture to achieve in medicinal chemistry1. In contrast to electronic...
Structures corresponding to 4 with main group fragments have been studied with the MNDO method (4: ML2 = AlH2, BH2, CH2+; R = H). For comparison the pyramidal structure 12, a D2h structure 14, and the planar six-membered ring 15 were also included. 14 was found to be the most ...
(bottom) illustrate that CO2forms a molecular complex with two K+ions, which are also partially desolvated. At the TS, CO2is partially reduced to a bent CO[Math Processing Error]20.44−, which is bound to two interfacial ions closely, and the C-Au distance is 2.74 Å. Compared to ...

Crystallographic analyses of 1a,b indicate that these complexes have a distorted octahedral geometry around Ti, and the O atom in the alkoxo ligand is coordinated to two Ti atoms. The similar reactions of [(HO-2,4-tBu2C6H2-6-CH2)2(HOCH2CH2)]N with Ti(OR')4 afforded the monomeric ...
近日,华南理工大学黄飞/刘春晨团队在期刊ACS Energy Letters上发表题为“C‑Shape or S‑Shape? The Molecular Geometry Control of Fused-Ring Nonfullerene Acceptors for Lower Energy Loss in Organic Solar Cells”的文章。该文章设计并合成了C型和S型的非富勒烯受体C-F及S-F,C-F和S-F表现出几乎相同的...
