Reusable resin plug-bound palladium catalysts for organic synthesis
摘要:
Resin plugs, a unique and conveniently handled form of resin, prepared by sintering high-density polyethylene (HDPE) with pre-functionalised resins, were derivatised and loaded with palladium(0). These 'plugs' were used in the preparation of a Suzuki reaction based library and the removal of allyl ester protecting groups. The 'plugs of catalyst' were easily separated from the reaction mixture and were re-used multiple times with minimal loss of activity. (C) 2003 Elsevier Science Ltd. All rights reserved.
The present invention provides a carbazole compound represented by the following formula (I):
wherein each Ar
1
independently represents a substituted or unsubstituted monovalent aromatic group or an aromatic group containing a heteroring, and R
1
and each R
2
independently represent a hydrogen atom, an alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group.
