The alkylation of alcohols and polyols has been investigated with alkylphosphates in the presence of a Lewis or Brønsted acid catalyst. The permethylation of polyols was developed under solvent‐free conditions at 100 °C with either iron triflate or Aquivion PW98, affording the isolated products in yields between 52 and 95 %. The methodology was also adjusted to carry out peralkylation with longer alkyl chains.

在路易斯或布朗斯台德酸催化剂存在下多元醇与磷酸三甲酯的甲基化

已经在路易斯或布朗斯台德酸催化剂的存在下用烷基磷酸酯研究了醇和多元醇的烷基化反应。多元醇的全甲基化反应是在无溶剂条件下于100°C时使用三氟甲磺酸铁或Aquivion PW98进行的，分离后的产物收率在52％至95％之间。还对方法进行了调整，以使用更长的烷基链进行全烷基化。
