Abstract:
η6-Dihydronaphthalene tricarbonylchromium(0) complexes and η6-indene tricarbonylchromium(0) have been prepared and subjected to Pd(0) catalysed reactions with iodoarenes. The reaction of η6-dihydronaphthalene tricarbonylchromium(0) complexes with iodoarenes under Jeffery conditions leads after decomplexation to triarylated products. The stereo- and regiochemistry of these products could be affirmed by an X-ray crystal structure. The η6-dihydronaphthalene unit can be part of more complicated structures such as of estrone derived compounds without changing the course of the reaction. The reaction of η6-indene tricarbonylchromium(0) with iodoarenes, however, leads to benzophenones, where the indene unit is not incorporated.
