N,N- and N,O-Bidentate-Chelation-Assisted Alkenyl C–H Functionalization Open
Chelation-assisted olefinic C–H functionalization has been demonstrated to be a powerful method of constructing multi-substituted alkenes from simpler ones. This strategy produces complex alkenes in a regio- and stereoselective manner, fol…

Lattice‐Confined Sn Sites Stabilizing Pt Catalysts in Oxidation‐Reduction Cycles for <i>n</i>‐Heptane Reforming and Propane Dehydrogenation Open
Supported Pt as catalysts have been applied for decades in industrial naphtha reforming and light alkane dehydrogenation but suffer from low stability in continuous and frequent regeneration‐reaction cycles. In this work, highly stable Pt …

Chelation-assisted multiple and relay C–H functionalization of unactivated aliphatic <i>E</i> -alkenes Open
We report the first sequential and relay C(sp 2 )–H functionalization of unactivated aliphatic E -alkenes to afford complex polyenes and polyeneynes, allowing for a range of functionalizations including alkenylation, hydroalkenylation and …

Novel lignin α-O-4 derived hydrogen donors in CQ-based photoinitiating systems for dental resins Open
The purpose of this work is to explore the properties of the lignin-derived amine-free photoinitiating systems (PISs) during the curing process. Four novel hydrogen donors (HD1, HD2, HD3, and HD4) derived from lignin α-O-4 structural were …
