Rhodium-Catalyzed Si-F Exchange Reaction between Fluorobenzenes and a Disilane. Catalytic Reaction Involving Cleavage of C-F Bonds

The reaction of functionalized fluorobenzenes, such as fluoroacetophenones and (fluorophenyl)oxazolines, with Me3SiSiMe3 in the presence of a catalytic amount of a rhodium complex results in a site-selective Si-F exchange to give ortho-(trimethylsilyl)fluorobenzenes. The reaction involves cleavage of C-F bonds.
