Abstract
The sterically congested, rigid, C3 symmetric phosphites (2a−e) have been synthesized by reaction of PCl3 with the corresponding tris(3,5-dialkyl-2-hydroxyphenyl)methanes (3,5-di-tert-butyl; 3-tert-butyl-5-methyl; 3,5-di-tert-pentyl; 3-adamantyl-5-methyl; 3,5-dimethyl) and characterized. The arsenite derivative (3b) of tris(3-tert-butyl-5-methyl-2-hydroxyphenyl)methane was similarly prepared by reaction with AsI3. Both the phosphite 2a and the arsenite derivative 3b have been examined by single-crystal X-ray analyses. Metal complexes (4−6) of the phosphites were prepared by reaction of the phosphite with [PdCl2(cod]) (cod = 1,5-cyclooctadiene), [PdCl(η3-C3H5)]2 and [Rh(CO)2(acac)] (acac = acetylacetonate), respectively, and examples of each are represented by X-ray structure determinations.
