The synthesis of functionalized carbazoles through gold-catalyzed deacylative cycloisomerization of 3-acylindole/ynes is described. A mechanistic proposal for these transformations involving a novel carbonyl group facilitated heterolytic fragmentation upon the loss of an acylium ion intermediate is presented. The eliminated acylium ion species could be trapped by the organogold intermediate to afford
