Preparations and Sulfurization Reactions of (2,4-Di-t-butyl-6-methoxyphenyl)phosphine and 1-(2,4-Di-t-butyl-6-methoxyphenyl)-2-(2,4,6-tri-t-butylphenyl)diphosphene
Preparation and Properties of Fluorenylidene(phenyl)phosphines Bearing Bulky Groups with Electron-Donating Substituents in the Ortho Position on the Phenyl Group
Fluorenylidene(phenyl)phosphines having bulky substituents with an electron-donating group in the o-position on the phenyl group were prepared and their properties were compared. The prepared materials included 2,4-di-t-butyl-6-methoxyphenyl, 2,4-di-t-butyl-6-(phenoxymethyl)phenyl, 2,4-di-t-butyl-6-(dimethylamino)phenyl, or 2,4-di-t-butyl-6-(2-phenylethyl)phenyl. The diphosphenes and dithioxophosphoranes
