摘要

The organomagnesium complex nBu2iPrMgLi, readily prepared from nBuLi and iPrMgCl (2: 1), is quite efficient for the bromine–magnesium exchange of 5-bromo-2-picoline under noncryogenic conditions (at− 10° C). The resulting picolylmagnesium complex reacts with various electrophiles to afford functionalized picolines.
