New and efficient method for the preparation of medium-sized lactones from the corresponding ω-hydroxycarboxylic acids

Article abstract of DOI:10.1246/cl.1997.187

Medium-sized lactones are prepared in good yields on treating monomeric cyclic silyl siloxycarboxylates, prepared in situ from ω-hydroxycarboxylic acids and 1,2-bisdimethylsilylbenzene using RhCl(PPh₃)₃ catalyst, with an active catalyst of dimethylsilylbis(trifluoromethanesulfonate).
