Versuchsvorschrift

Other cyclic phosphites prepared as described above were 2-[4-methyl-2,6-bis(1,1-dimethylethyl)phenoxy]-6-methyl-4H-1,3,2-benzodioxaphosphorin, melting point 117°-123° C., molecular weight 486, by the reaction of 4-methyl-6-hydroxymethylphenol with 2,6-di-t-butyl-4-methylphenylphosphorodichloridite; 2-[2,4,6-tris(1,1-dimethylethyl)phenoxy]-6,8-bis(1,1-dimethylethyl)-4H-1,3,2-benzophosphorin, melting point 166°-255° C., molecular weight 526, by the reaction of 2,4,6-di-t-butyl-6-hydroxymethylphenol with 2,4,6-tri-t-butyl-phenylphosphorodichloridite; and 2-[2,4,6-tris(1,1-dimethylethyl)phenoxy]-8-(1,1-dimethylethyl)-4H-1,3,2-benzodioxaphosphorin, melting point 120°-127° C., molecular weight 470, by the reaction of 2-t-butyl-6-hydroxymethylphenol and 2,4,6-tri-t-butyl-phenylphosophorodichloridite. The structures were confirmed by Nuclear Magnetic Resonance and Infra-Red Analysis.
