Iron‐Catalyzed Vinylogous Michael Addition of Boron Dipyrromethene (BODIPY) Derivatives to para‐Quinone Methides

We report herein an effective method for an iron‐catalyzed vinylogous Michael addition of BODIPY derivatives to para‐quinone methides under mild conditions. The corresponding BODIPY‐derived diarylmethane compounds were obtained in 65–93 % yields. This method is featured by its inexpensive catalyst,...

Description
Summary:We report herein an effective method for an iron‐catalyzed vinylogous Michael addition of BODIPY derivatives to para‐quinone methides under mild conditions. The corresponding BODIPY‐derived diarylmethane compounds were obtained in 65–93 % yields. This method is featured by its inexpensive catalyst, simple reaction condition and broad substrate scope. An iron‐catalyzed vinylogous Michael addition reaction of p‐QMs and BODIPYs afforded various adducts in good to excellent yields under mild condition. Using easily available and low‐cost FeCl3 as catalyst makes this method more practical and attractive for potential applications.
