资源简介：
Iron-promoted difunctionalization
of α,α-diaryl and
α-aryl-α-alkyl allylic alcohols has been efficiently achieved
by means of N-(phenylseleno)phthalimide
(N-PSP) under mild conditions. An in situ generated
phenylselenium cation (PhSe+) was added to the olefinic
CC bond to initiate the regioselective phenylselenylation
with concomitant 1,2-aryl migration, following a migration preference
contrary to the well-known radical pathway. Hydrazonation of the resultant
alkene difunctionalization products, that is, α-aryl-β-phenylselenyl
ketones, and subsequent copper-catalyzed dehydroselenylation efficiently
afforded functionalized 2-pyrazoline derivatives.
