Multiple Bonds between Main Group Elements and Transition Metals, CXXIX[1]. - Chlorotrioxorhenium. Novel Syntheses, Reactions, and DerivativesChlorotrioxorhenium (1a) and homologs of formula X-ReO3 (1b-e) are generated from Re2O7 and either ZnX2, (n - C4H9)3SnX, [(n-C4H9)4N]X, or [(C6H5)4P]X in clean reactions. Compounds 1a-f form with stable six-coordinate adducts XReO3 ·L (2a-f, 3a, 4a, 5a: L = N,N′-ligand) upon addition of the free ligand L, e.g. 2,2′-bipyridine. 1a is readily alkylated by means of SnR4 or ZnR2 to form organorhenium(VII) oxides in good yields. These synthetic routes have the advantage to proceed under very mild conditions. The adducts of 2,2′-bipyridine with halorhenium(VII) oxides show characteristic thermogravimetric (TG) behavior that reflects the volatility of the uncoordinated complexes X-ReO3.
