Article abstract of DOI:10.1016/S0022-328X(00)88971-8

The stereochemistry of the nucleophilic substitution of various functional 1,2-dimethylgermacyclopentanes MeC4H7Ge(Me)X (X = Cl, OR, SR, NR2, PR2) by reducing reagents (LiAlH4, LiBH4), Grignard and organolithium compounds is studied.It depends both on the nucleophile and the leaving group.The results agree completely with those obtained in silicon series using optical NpPhRSi^*X or geometrical MeC4H7Si(Me)X isomers.
