TRANSITION METAL ?-COMPLEXES IN ORGANIC SYNTHESIS 5. CROSS-COUPLING OF ORGANOMANGANESE COMPOUNDS WITH ALKENYL IODIDES

Kasatkin, A. N.,Romanova, T. Yu.,Tsypyshev, O. Yu.,Tolstikov, G. A.,Lomakina, S. I.

, p. 2410 - 2415 (1989)

Aryl organomanganese compounds ArMnX and Ph3MnLi (Ar = Ph, p-MeC6H4, p-MeOC6H4, p-ClC6H4, p-BrC6H4, α-naphthyl; X = Cl, Br) react with alkenyl iodides RR1C=CR2I (R = H, Pr, Bu, i-Bu, C6H13, CH2=CHCH2, Ph; R1 = H, Pr, C5H11; R2 = H, Pr, SiMe3) in THF at 0-20 deg C to give cross-coupling products RR1C=CR2Ar in high yields.
