Um. Dzhemilev et al., CATALYTIC SYNTHESIS AND TRANSFORMATIONS OF MAGNESACYCLOALKANES .3. CYCLOMAGNESATION OF NORBORNENES CATALYZED BY CP2ZRCL2, Russian chemical bulletin, 42(1), 1993, pp. 149-153
Catalytic cyclometallation of bicyclo[2.2.1]hept-2-ene, spiro{bicyclo[
2.2.1]hept-2-ene-7.1'-cyclopropane} and endo-tricyclo[5.2.1.0(2,6)]dec
a-3,8-diene (dicyclopentadiene) with R2Mg (R = n-Pr, n-Bu) leading to
the formation of polycyclic magnesacyclopentanes (MC) has been studied
. The yield of MC and the selectivity of the reaction have been shown
to depend on the ratio of starting reagents, the solvent, and temperat
ure. The most probable scheme of the transformation studied is propose
