摘要：

1-Butene is transformed in a continuous flow reactor over tungsten hydrides precursor W-H/Al(2)O(3), 1, giving a promising yield into propylene at 150 degrees C and different pressures. Tungsten carbene-hydride single active site operates as a "bi-functional catalyst" through 1-butene isomerization on W-hydride and 1-butene/2-butenes cross-metathesis on W-carbene. This. active moiety is generated in situ at the initiation steps by insertion of 1-butene on tungsten hydrides precursor W-H/Al(2)O(3), 1 followed by alpha-H and beta-H abstraction.
