The host 9-(3-chlorophenyl)-9H-xanthen-9-ol forms inclusion compounds with benzene, toluene, p-xylene, and pyridine. Their structures have been elucidated and correlated with their kinetics of desolvation and guest exchange.

N-lodo- and N-bromo-p-nitrobenzamide have been shown to react with various organic acids to form the respective acyl or sulfonyl hypoiodites or hypobromites. These readily add to double bonds under mild conditions to yield trans-vic-halogeno esters.
