A new palladium/copper catalytic procedure for the C3-alkenylation of free NH-indoles is reported. Using homogeneous or heterogeneous hetero-bimetallic [Pd/Cu]-catalysts under mild reaction conditions (10mol% Pd-catalyst and 10mol% Cu-catalyst, 70°C, air), substituted indoles are fully (58–82% isolated yields) and selectively (75–100% selectivity) converted to the expected 2-substituted-3-vinyl indoles.
