摘要
The organomagnesium complex "(Bu2PrMgLi)-Pr-i, readily prepared from "BuLi and (PrMgCl)-Pr-i (2:1), is quite efficient for the bromine-magnesium exchange of 5-bromo-2-picoline under noncryogenic conditions (at -10 degrees C). The resulting picolylmagnesium complex reacts with various electrophiles to afford functionalized picolines. (c) 2006 Elsevier Ltd. All rights reserved.
