PROCESSES FOR PREPARATION OF 2-ALKYL-2-ADAMANTYL ESTERS |
摘要 |
<p>A magnesium halide salt of a 2-alkyl-2-adamantanol is reacted with a carboxylic acid halide such as acrylic chloride or the like in the presence of a tertiary amine to produce a 2-alkyl-2-adamantyl ester (the first invention). A 2-alkyl-2-adamantanol is reacted with a carboxylic acid such as acrylic acid or the like in the presence of an acid catalyst such as concentrated sulfuric acid or the like and a drying agent composed of an acidic or neutral inorganic compound (e.g. magnesium sulfate) which is a solid at ordinary temperature in a dried state or of a water-absorbing high-molecular compound, to produce a 2-alkyl-2-admantyl ester (the second invention). The above ester is important as a raw material for a resist for semiconductor production.</p> |
