Hammad, M. published the artcileSynthesis of some new pyrazolones and benzimidazole acetonitriles derived from xanthene, Product Details of C19H14O2, the publication is Egyptian Journal of Chemistry (1987), 29(6), 617-22, database is CAplus.
Cyclizations of α-cyano xanthenyl hydrazides I [R = H, Me, PhCH2, Ph, 4-MeC6H4; R1 = CH(CN)CONHNH2] gave xanthenylpyrazolones II. Condensation of xanthenol I (R same as above, R1 = OH) with benzimidazol-2-ylacetonitrile gave benzimidazolylxanthenylacetonitriles III.
