An efficient iodine pentoxide-triggered iodocarbocyclizations for the synthesis of iodooxindoles in water

03-Jul-2018 | Ming-Zhong Zhang; Xin Wang; Ming-Ying Gong; Lin Chen; Wenbin Shi; Shu-Hua He; Yong Jiang; Tieqiao Chen, Organic & Biomolecular Chemistry, 2018

An efficient iodocarbocyclization of alkenes for the synthesis of iodooxindoles has been developed. This reaction proceeds in a chemoselective manner and shows excellent tolerance of various functional groups, including a chemosensitive hydroxymethyl group. Nonmetal inorganic iodine pentoxide was ...

The C‒C to C=C conversion within a supramolecular framework of tetrathiafulvalene: a confinement effect and an oxygen related dehydrogenation

20-Jun-2018 | Ping Zhang; Peng Huo; Xuan Zhang; Qin-Yu Zhu; Jie Dai, Chemical Communication, 2018

Dehydrogenation of alkanes to generate alkenes is catalyzed by a supramolecular framework of a tetrathiafulvalene derivative under ambient conditions, and a confinement effect of the framework is responsible for the oxidation reaction in the presence of oxygen.
