Article abstract of DOI:10.1016/S0040-4039(99)00827-8

Ring opening of various spiroketals with triphenylphosphine dihalides under neutral conditions produced ω-halo-enolethers in good to excellent yield. The method transformed even the very stable spiroketal of hecogenin acetate at temperatures below any previously reported for such isomerative opening.
