PH-functional o-phosphinophenols - Synthesis via methoxymethylethers and screening tests for Ni-catalyzed ethylene polymerization

Various primary and secondary 2-phosphinoaryl methoxymethylethers were prepared via orthometallation of methyl- and methoxy-substituted aryl methoxymethylethers and subsequent reaction with aminochlorophosphines, followed by alcoholysis and reduction with excess LiAlH4. Incomplete reduction provides 2-methoxymethoxy-substituted cyclotetraphosphines, isolated and characterized by X-ray crystal structure analysis in one case. An example of the facile P-alkylation of primary to secondary representatives is also given. Secondary 2-phosphinophenols, obtained by selective cleavage of the MOM-protection group, and even the primary 2-phosphino-4-methylphenol react with Ni(COD)2 to form ethylene polymerization catalysts. 4-Methoxy groups cause a strong increase of the molecular weights and a bimodal molecular weight distribu tion of the polymerization products; neither effect is observed for tertiary phosphinophenolate/Ni polymerization catalysts.
