Samarium reagent-promoted formation of benzoins from diarylmethanones and DMF via a carbene rearrangement reaction

, p. 4867 - 4873 (2007/10/03)
Prompted by samarium metal in DMF with TMSCl or iodine as an activator, or by SmI2/THF system, diarylmethanones react readily with DMF to afford benzoins in moderate to good yields via rearrangement of aryl groups. As for asymmetric diarylmethanones, products resulting from the migration of either aryl group were obtained, where the migration of aryl groups shows certain priority.
Direct Formation of Benzoins from Diarylmethanones via a Rearrangement Reaction Promoted by Samarium Metal in DMF

, p. 445 - 448 (2007/10/03)
Diarylmethanones react readily with DMF when promoted by samarium metal in DMF with TMSCl or iodine as an activator, to afford benzoins in good to excellent yields via rearrangement of aryl groups. As for asymmetric diarylmethanones, products resulting from the migration of either aryl group were obtained, where the migration of aryl groups shows certain priority.
Bis-dithiobenzilnickel complexes for usae in near-infrared absorbing materials and benzoin derivatives as intermediates therefor

, (2008/06/13)
A benzoin compound is synthesized from phenylglyoxal and a substituted benzene, and the resulting benzoin compound is converted to a bis-thiobenzilnickel complex using phosphorus pentasulfide/nickel chloride. The resulting bis-thiobenzilnickel complex of Formula [1] and/or [2]: (wherein R1 to R5 are the same or different, and denote substituted or unsubstituted alkyl, cycloalkyl, alkoxy, aryl, aryloxy, halogen atom, or hydrogen atom, except for substituted or unsubstituted amino group and alkoxyalkoxy group. However, a case where all of R1 to R5 are hydrogen atoms is excepted.) contains two phenyl groups and two substituted phenyl groups and is useful as a near-infrared absorbing material in, for example, optical recording materials and molding compositions containing transparent resins.
