Methylrhenium trioxide is commercially available. It can be prepared by many routes, a typical method is the reaction of rhenium heptoxide and tetramethyltin: [1] Re 2 O 7 + (CH 3) 4 Sn → CH 3 ReO 3 + (CH 3) 3 Sn−O−ReO 3. Analogous alkyl and aryl derivatives are known.
Rhenium(VI) oxide has an appearance similar to that of copper. Rhenium(IV) oxide (or rhenium dioxide) is an oxide of rhenium, with the formula ReO 2. This gray to black crystalline solid is a laboratory reagent that can be used as a catalyst. It adopts the rutile structure. It forms via comproportionation: [4] 2 Re 2 O 7 + 3 Re → 7 ReO 2
Fresh catalyst is chlorided (chlorinated) prior to use. [citation needed] The noble metals (platinum and rhenium) are catalytic sites for the dehydrogenation reactions and the chlorinated alumina provides the acid sites needed for isomerization, cyclization and hydrocracking reactions.
It has offered products at heavy discounts, such as an LG UltraGear Gaming Monitor for $179, $70 lower than its original price, and JBL headphones for a 30% discount, at $69.99.
Bromopentacarbonylrhenium(I) is a precursor to other rhenium complexes. It reacts with zinc and acetic acid to give pentacarbonylhydridorhenium (HRe(CO) 5). [3]Re(CO) 5 Br + Zn + HO 2 CCH 3 → ReH(CO) 5 + ZnBrO 2 CCH 3
