Homogeneous Catalytic Aminocarbonylation of Iodoalkenes and Iodobenzene
Amino Acid Esters under Conventional Conditions and in Ionic Liquids. —
23- 058 with
Iodoalkenes (I) and (V) give exclusively the corresponding carboxamides on reaction
with amino esters both at normal and high CO pressure. The aminocarbonylation of (V)
is also performed in [bmim]PF6 or [bmim]BF4 ionic liquids and the ionic liquid—catalyst mixtures can be reused several times with only a small loss of activity. Iodobenzene (VII) reacts only at elevated CO pressure with amino esters and affords 2-oxocarboxamides as result of double CO insertion. — (MUELLER, E.; PECZELY, G.;
