Disilylation of Palladacycles that were Generated through the C−H Activation of Aryl Halides - 张扬会课题组

The reactions of various C,C‐palladacycles that were generated through the C−H activation of aryl halides with disilanes have been studied. The reaction of arylnorbornyl palladacycles, which were generated through a Catellani reaction, with hexamethyldisilane proceeded very efficiently to afford disilylated products. Palladacycles that were obtained through the remote C−H activation of aryl halides that contained a styrene moiety with an ether linkage also underwent a disilylation reaction with hexamethyldisilane. Furthermore, the reactions of dibenzopalladacyclopentadienes, which were generated from 2‐iodobiphenyls, with diphenyltetramethyldisilane were also investigated and a range of 2‐iodobiphenyls were disilylated in moderate yields.
