With the assistance of hydrogen bonds of the o-amino group, we have successfully tuned a coordination structure from a metal-organic polyhedron (MOP) to a two-dimensional (2D) metal-organic framework (MOF). The amino group forms hydrogen bonds with t

In this work, orthorhombic CoSe2 is fabricated by nitrogen doping into a cubic CoSe2 structure, in which the crystalline phase undergoes transformation. The doped atoms lead to the rotation of the Se22− group, and then the faults of phase change ca

Here, we describe an efficient and environmentally friendly synthesis of polycyclic N-heterocycles under electrochemical external oxidant-free conditions. The extent of the sequential electrochemical oxidative aromatization can be regulated with the

Herein we report a practical pinacol coupling reaction, in which ketones (aldehydes) react smoothly with Sm and TMSBr to afford the diol products with Sm(II) or (III) siliyl species generated in situ. This reported method affords poor yields for arom

Gas phase catalytic process with the advantages of simply product separation and maximized atom economy, which was a green path used in industrial production. At present, heterogeneous dehydrochlorination catalysts are facing challenge of rapid deact

A variety of chroman-4-one and indanone derivatives were conveniently synthesized from readily available cyclopropanols and alkenyl aldehydes via a silver catalyzed radical ring-opening/coupling/cyclization cascade. The reaction proceeded under mild

The selective construction of bicyclo[3.3.0]octan-1-ols and bicyclo[3.1.0]hexan-1-ols was achieved by using an allylSmBr/additive(s) system. By employing HMPA as the only additive, the momoallylation/ketone-alkene coupling occurred preferably and aff

The allylSmBr/HMPA/MsOH system has been found to be an efficient reagent for the “ester-alkene” coupling/cyclization cascade of readily available α-allyloxy esters. Oxobicyclo[3.1.0]hexane-1-ols were thus prepared in good to excellent yields and
