, p. 4482 - 4485 (2018)
Exchanging the bridging oxygen atom in rhodamine dyes with a dimethylsilyl group red-shifts their excitation and emission spectra, transforming orange fluorescent rhodamines into far-red Si-rhodamines. To study the effect of this substitution in other dye
Conformations of N,N-Bis(2-fluorophenyl)carbamoyl Chloride

, p. 4067 - 4072 (1989)
The structure of the title compounds has been examined by X-ray crystallographic and fluorine NMR methods.In the solid state the planes of the fluorophenyl rings are oriented at angles of 98 deg and 64 deg relative to the plane through the atoms of the carbamoyl chloride group.Fluorine NMR studies indicate that the conformational properties of the molecule in solution are similar to this.Fluorine NMR lineshape data were used to estimate the rates of roation of the fluorophenyl rings and the rate of rotation about the carbamoyl nitrogen-carbon bond.Observation of a large fluorine-fluorine coupling constant, likely the result of a through-space interaction, supports the conclusions regarding the conformations of this compound in solution.

A metabolism study of FK788 (2) led to the discovery of new diphenylcarbamoyl derivatives as prostacyclin mimetics without the PG skeleton. We designed and evaluated PGI2 mimetics based on blocking the main metabolic pathway of FK788. The new compound 7c was found to be equipotent to FK788 towards PGI2 agonist activity and metabolically more stable than FK788.
Ligands for metals as catalysts for carbon-carbon bond formation
-
Page/Page column 13, (2008/06/13)
The present invention provides a family of novel and stable ligands which chelate with a metal to form a complex. The ligand contains a ring, particularly a phenyl group, or a hydrocarbon group which links an amino group and PR1R2, NR1R2, OR1, SR1, or AsR1R2 group such that the structure of the ligand can be stabilized.

Page/Page column 3-4; 12, (2010/02/15)
The present invention relates to a complex comprising a novel and stable ligand and a metal center. The ligand contains a ring, particularly a phenyl group, or a hydrocarbon group which links an amino group and PR1R2, NR1R2, OR1, SR1, or AsR1R2 group such that the structure of the ligand can be stabilized.
