Abstract

The reactions of dodecahydro-closo-dodecaborate oxonium derivatives with various phenols resulted in phenoxy-undecahydro-closo-dodecaborates in high yields. Using this method, a phthalocyanine zinc(II) complex containing four (B₁₂H₁₂)^2- species was prepared in high yield. The compound shows good photocatalytic activity. The combination of boron cages and phthalocyanines makes this compound useful for boron neutron capture therapy for cancer and photodynamic tumor therapy.
