Abstract

original image

Organostibine and organobismuthine groups at the living polymer ends are selectively transformed to the corresponding carbanions by a heteroatom–metal exchange reaction (transmetallation). Due to the high reactivity of these heteroatom species, the exchange reaction takes place even in the presence of various polar functional groups, which potentially react with organometallic reagents. For more details see the Full Paper on page 5272 ff., by S. Yamago et al.
