用于形成1,3,5,7-四烷基-6-(2,4-二甲氧基苯基)-2,4,8-三氧杂-6-磷杂金刚烷的方法
Abstract:
一种用于形成1,3,5,7-四烷基-6-(2,4-二甲氧基苯基)-2,4,8-三氧杂-6-磷杂金刚烷的方法包括：获得包含醚制溶剂和氢化铝的溶液，将二氯(2,4-二甲氧基苯基)膦添加到所述溶液中以产生2,4-二甲氧基苯基膦，和使所述2,4-二甲氧基苯基膦与包含二酮的酸性混合物反应以产生1,3,5,7-四烷基-6-(2,4-二甲氧基苯基)-2,4,8-三氧杂-6-磷杂金刚烷。在整个方法中，所述溶液的温度为大于-20℃至50℃。另一种用于形成1,3,5,7-四烷基-6-(2,4-二甲氧基苯基)-2,4,8-三氧杂-6-磷杂金刚烷的方法包括：获得二氯(2,4-二甲氧基苯基)膦，通过将所述二氯(2,4-二甲氧基苯基)膦添加到包含至少一种溶剂和氢化铝的溶液中来形成2,4-二甲氧基苯基膦，使所述2,4-二甲氧基苯基膦与混合物反应以产生1,3,5,7-四烷基-6-(2,4-二甲氧基苯基)-2,4,8-三氧杂-6-磷杂金刚烷。所述混合物包括选自由路易斯酸、磺酸布朗斯台德酸和其混合物组成的组的酸；芳香族或非芳香族烃；和乙酰丙酮。
Abstract(English):

A method for forming 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane includes obtaining a solution comprising an ethereal solvent and an aluminum hydride, adding dichloro(2,4-dimethoxyphenyl)phosphine to the solution to produce 2,4-dimethoxyphenylphosphine, and reacting the 2,4-dimethoxyphenylphosphine with an acidic mixture comprising diones to produce 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane. The solution has a temperature from greater than -20 C to 50 C throughout the method. Another method for forming 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane includes obtaining dichloro(2,4-dimethoxyphenyl)phosphine, forming 2,4-dimethoxyphenylphosphine by adding the dichloro(2,4-dimethoxyphenyl)phosphine to a solution comprising at least one solvent and an aluminum hydride, reacting the 2,4-dimethoxyphenylphosphine with a mixture to produce 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane. The mixture includes an acid selected from the group consisting of Lewis acids, sulfonic Bronsted acids, and mixtures thereof, an aromatic or non-aromatic hydrocarbons; and acetylacetone.
