Amination and amidation of bromoindole, 6-bromo-1,2,3,4-tetrahydrocarbazol-1-one, and 8-bromo-2,4,5,6-tetrahydro-1H-pyrazino[3,2,1-jk]carbazole derivatives was effected in the presence of palladium complexes. The use of the catalytic system Pd2dba3⋅CHCl3-2-[di(tert-butyl)phosphino]biphenyl in the amination and of Pd2dba3⋅CHCl3-Xantphos [or 3,5-(CF3)2Xantphos] in the amidation ensured moderate to high yields of the corresponding products.
