Reactivity of main-group–transition-metal bonds. Part 7. Kinetics of the reaction of mercury(II) halides with compounds containing tin–chromium, –molybdenum, –tungsten, –manganese, –rhenium, and –iron bonds

Abstract

The kinetics of the cleavage of tin–transition-metal bonds by mercury(II) halides have been measured for the following reactions: [Cr(cp)(CO)₃(SnMe₃)] with HgBr₂; [Mo(cp)(CO)₃(SnMe₃)] with HgX₂(X = Cl, Br, or l); [W(cp)(CO)₃(SnMe₃)] with HgBr₂; [Mn(CO)₅(SnMe₃)] with HgX₂(X = Cl, Br, or l); [Re(CO)₅(SnMe₃)] with HgBr₂; [Fe(cp)(CO)₂(SnMe₃)] with HgX₂(X = Cl, Br, or l)(cp =η-cyclopentadienyl). The reactions proceed via an adduct formed between the reactants, and the reactivity patterns resemble those for iodination.
