Relations between 77Se NMR chemical shifts of (phenylseleno)-benzenes and their molecular structures derived from nine X-ray crystal structures
Oddershede, Jette,Henriksen, Lars,Larsen, Sine
, p. 1053 - 1060 (2003)
An extensive library of 77Se chemical shifts have been generated from the NMR measurements on substituted (phenylseleno)benzenes, including 33 new compounds. The variation in chemical shifts cover 265 ppm ranging from 446 to 181 ppm. Crystal st
Ammonium Salt-Catalyzed Highly Practical Ortho-Selective Monohalogenation and Phenylselenation of Phenols: Scope and Applications

An ortho-selective ammonium chloride salt-catalyzed direct C-H monohalogenation of phenols and 1,1′-bi-2-naphthol (BINOL) with 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) as the chlorinating agent has been developed. The catalyst loading was low (down to 0.01 mol %) and the reaction conditions were very mild. A wide range of substrates including BINOLs were compatible with this catalytic protocol. Chlorinated BINOLs are useful synthons for the synthesis of a wide range of unsymmetrical 3-aryl BINOLs that are not easily accessible. In addition, the same catalytic system can facilitate the ortho-selective selenylation of phenols.

Direct sulfenylation and selenylation of phenols using a stoichiometric amount of FeCl3 under an oxygen atmosphere has been developed. The chalcogenated phenols were shown to be suitable for preparing S- and Se-containing compounds using the reaction of the remaining hydroxy group.

Direct Selenation of Electron-Rich Aromatic Compounds with (Phenylseleno)dimethylsulfonium Tetrafluoroborate
Gassman, Paul G.,Miura, Asako,Miura, Takashi
, p. 951 - 954 (2007/10/02)
(Phenylseleno)dimethylsulfonium tetrafluoroborate was found to be a highly reactive selenating agent for electron-rich aromatic compounds such as aromatic amines, phenols, and aromatic ethers.Reaction took place readily at 0-25 deg C to give ca. 50percent yields of substitution para to the activating substituent.In general, anilines gave better yields then anisoles or phenols.
