It is well known that ester-based lubricants are one of the useful synthetic lubricants having high flame retardancy and biodegradability. We have succeeded in the regioselective oligomerization of various α-olefins using Zr(IV) complexes supported by [OSSO]-type ligands. Herein, we present the synthesis of novel branched diesters, as ester-based lubricant precursors, by the oligomerization of ω-siloxy-α-olefins with the Zr(IV) complex.
