Fluoroalkylation of aromatic compounds with per(poly)fluoroalkyl chlorides initiated by sodium dithionite in DMSO
摘要:
Treatment of electron-rich aromatic and heteroaromatic. compounds with per(poly)fluoroalkyl chlorides in the presence of sodium dithionite in DMSO gives the corresponding fluoroalkylated products in moderate to good yields. The structures and yields of products depend mainly on the position and electron-donating ability of the substituents on the aromatic compounds. (C) 2001 Elsevier Science B.V. All rights reserved.

Bioaffinity and ion-exchange separation methods are provided along with liquid supports utilized in these methods. The support is based on an inert carrier with ligands or binders attached to its surface. Methods for preparing such supports and their use in capturing neutral and charged target molecules from samples and in analytical applications are also provided.
