How is 1-Piperidinyloxy,4,4'-[(1,10-dioxo-1,10-decanediyl)bis(oxy)]bis[2,2,6,6-tetramethyl- (CAS: 2516-92-9) typically synthesized?

This compound is typically synthesized through a multistep procedure involving the ring-opening polymerization of a piperidine derivative with 1,10-decanediol, followed by a selective oxidation step. The reaction is catalyzed by transition metals like ruthenium, and the yield is generally high, around 90%. The synthesis requires precise control of reaction conditions to achieve the desired product.
