发明名称 PROCESS FOR PREPARATION OF 3,5-BISALKYLPHENOLS
摘要 <p>The invention provides a process for producing a 3,5-bisalkylphenol (2) according to the following reaction scheme: <CHEM> (wherein R<1> represents a hydrogen atom, an alkali metal atom, an alkaline earth metal atom, or a hydroxyl-protecting group (other than methyl group); R<2> represents a C1 to C5 lower alkyl group or an optionally substituted phenyl group; and each of R<3> and R<4>, which may be identical to or different from each other, represents a lower alkyl group, an aralkyl group, or an aryl group); a carbinol compound (1); and a process for producing the carbinol compound. The production process of the present invention enables efficient and safe production of a variety of 3,5-bisalkylphenols including 3,5-diisopropylphenol, which are important as synthesis intermediates for drugs and agricultural chemicals, in shorter steps at high purity in high yield, thus contributing to consistent supply of drugs and agricultural chemicals.</p>
