Breath‐taking activation: Stereoregular carbene polymerization proceeds via cationic [(allyl)RhIII–polymeryl]+ species. These are most efficiently generated by oxygenation of the [(diene)RhI] precatalysts, which involves an unusual rearrangement of 2‐rhodaoxetane intermediates. This discovery gives detailed insight in the reaction mechanism.
令人叹为观止的活化:通过阳离子[(烯丙基)Rh III –聚合基] +物质进行立体异构的卡宾聚合反应。这些是由[(diene)Rh I ]预催化剂的氧化最有效地产生的,这涉及到2-rhodaoxetane中间体的异常重排。这一发现为反应机理提供了详细的见解。
