Microencapsulated Cu(acac)2:: a recoverable and reusable polymer-supported copper catalyst for aziridination of olefins

Microencapsulated copper(II) acetylacetonate was prepared and used in the aziridination of alkenes employing [N-(p-tolylsulfonyl)imino]phenyliodinane (PhI=NTs) as the nitrogen source. Microencapsulated copper(II) acetylacetonate [MC-Cu(acac)(2)] catalyst was reused for several cycles with consistent activity. (C) 2003 Elsevier Ltd. All rights reserved.
