Transient [3,3] Cope rearrangement of 3,3-dicyano-1,5-dienes: computational analysis and 2-step synthesis of arylcycloheptanes. [PDF]

, 2018
A simple and modular route to arylcycloheptene scaffolds is reported. The two-step route from Knoevenagel adducts and allylic electrophiles is made possible through the design of a Cope rearrangement that utilizes a "traceless" activating group to ...

A novel sulfur‐containing photoinitiator based on benzophenone derivatives for rapid photopolymerization

Smart Molecules, EarlyView.
This study develops a series of unimolecular photoinitiators, BP‐S1‐5, by incorporating hydrogen‐donating groups into a benzophenone framework. This method reduces the reliance on co‐initiators, and enables BP‐S1‐5 with efficient photoinitiation and excellent molding capability.
