    • It seems that the hydroxamic acid derivatives of rhodamine B and fluorescein are less likely to promote ring opening of the chlorinated spirocyclic intermediates to give the corresponding acyl nitroso compounds. From our previous studies, we found that the irreversible spirocyclic ringopening reaction is generally favored by NHEt over NEt2 or OH at the xantene ring see ref 10a

    • It is not easy to directly compare properties of 1 with those of the known probes for HOCl. But we believe that the readily available rhodamine amide derivative 1 could find broad biological applications.
