A hexacarbene complex derived from 1,1′-methylenebis(4-butyl-1H-1,2,4-triazolium) diiodide. Synthesis, characterization and catalytic activity

The synthesis and characterization of a hexacarbene complex (1) derived from 1,1′-methylenebis(4-butyl-1H-1,2,4-triazolium) diiodide are reported. The organic backbone was constructed prior to the introduction of metal atoms by reaction with palladium(II) acetate. The catalytic activity of 1 in a Heck reaction has been tested.
