, p. 1212 - 1218 (2001)
4,4′-(Fluorene-9,9-diyl)diphenol (1) is demonstrated to be both an effective clathrate host in itself and a useful construction element to form a rigid macrocyclic host compound 2. The X-ray crystal structures of 1 and of its inclusion compounds with acetonitrile (1 : 1) and ethanol (1 : 2) as well as the inclusion compound of 2 with dimethyl sulfoxide (1 : 4) and the mixed-guest inclusion compounds of 2 with 2-picoline, 3-picoline or 4-picoline and acetone (2 : 2 : 1) are reported. Inclusion compounds of 1 with acetonitrile and ethanol are studied by thermal analysis.
Palladium-copper catalyzed C(sp3)-C(sp2) bond C-H activation cross-coupling reaction: Selective arylation to synthesize 9-aryl-9: H -xanthene and 9,9-diaryl-xanthene derivatives

, p. 84748 - 84751 (2016/10/12)
A novel cooperatively catalyzed C(sp3)-C(sp2) bond C-H activation cross-coupling reaction has been developed. A series of 9-aryl-9H-xanthenes and 9,9-diaryl-xanthenes were selectively synthesized in moderate to good yields by control
