The Fujiwara hydroarylation of alkynes was reinvestigated. Reactions were monitored by 1H NMR spectroscopy, by electrospray ionization mass spectrometry (ESI/MS), and through reactions carried out in the gas phase using MS/MS experiments.

CH bond functionalization of aromatic heterocycles with chelating dicarbene palladium(II) and platinum(II) complexes
Chelatingdicarbenecomplexes of palladium(II) and platinum(II) catalyse at room temperature with 1% catalyst loading the reaction of ethyl phenylpropiolate with aromatic heterocycles to yield synthetically useful intermediates for fine chemicals without the need to use prefunctionalized substrates. The reaction outcome was found to be strongly dependent on the nature of the anionic ligands at the
