• Associated context:

  Interestingly, the catalyst could be recycled by a facile procedure to maintain high activity (eq 2). After the reaction of aqueous ammonia with 4a catalyzed by 3 was conducted, aqueous ammonia (CAS 7664-41-7) and dichloromethane (CAS 75-09-2) were added to the system, and the organic and aqueous phases were separated.
