Reactivity of 5-alkynyl-3,4-dihydro-2H-pyrroles with Au(III) Route to vinylgold(III) complexes, aurocycles by cyclisation of these complexes and ML complexes

Abstract : The reaction of 5-alkynyl-3,4-dihydro-2H-pyrroles (imine) with AuCl3 led to the synthesis of the vinyl gold(III) complexes 3 that could give the aurocycles 4 with an excess of AuCl3. In the base presence the dimerization of 4 was observed leading to 5. If NaAuCl4 was used as gold(III) source a ligand exchange was observed leading to the complexes 6. Nucleo-philicity of both nitrogen atom and alkyne function as well as imine-enamine tautomerism were involved to explain the formation of 3.
