Multiple Bonds between Main Group Elements and Transition Metals, CXXIX [1] . — Chlorotrioxorhenium. Novel Syntheses, Reactions, and Derivatives Chlorotrioxorhenium ( 1a ) and homologs of formula X‐ReO 3 ( 1b–e ) are generated from Re 2 O 7 and either ZnX 2 , ( n ‐ C 4 H 9 ) 3 SnX, [( n ‐C 4 H 9 ) 4 N]X, or [(C 6 H 5 ) 4 P]X in clean reactions. Compounds 1a–f form with stable six‐coordinate adducts XReO 3 ·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 SnR 4 or ZnR 2 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‐ReO 3 .
