Abstract
Starting from the chloro-rhodium(I) complex. RhCl[P(eta (2)-C7H7)(3)] (1), several salts such as (Rh[P(eta (2)-C7H7)(3)]) X-+(-) (X- = BF4- (2). CF3CO O (5). CF3SO3- (7)) and (Rh(L-L)[P(eta (2)-C7H7)(2)(C-7,H-7)]) +BF4- (L-L = 1,10-phenanthroline (4a) or 2,2'-bipyridine (4b)) have been prepared. The reaction of 1 with trimethylsilyl trifluoromethane sulfonate, CF3SO2-OSiMe3 , has been found to involve a stereospecific 4:2 Diels-Alder cycloaddition between two coordinated cyclohepta-2,4,6-trienyl substituents to give a din uclear rhodium(III) complex, ( Rh-2[P(eta (3)-C14H15)(C7H7)](2)(mu -Cl)(3)) (+)(CF3SO3-) (8), which has been characterized by NMR spectroscopy and an X-ray structure analysis.
