1,3-Benzodithiole tetraoxide (BDT) 4 is more reactive in alkylation reactions than the commonly used bis(benzenesulfonyl)methane (1). This is demonstrated notably in dialkylations with sterically demanding alkyl halides. Besides its ready access and larger scope of applications, BDT has two other advantages over 1, a lower molecular weight and higher crystallinity of its alkylated derivatives. As in

The present invention relates to a process for preparing 4-cyclohexyl-2-methyl-2-butanol. The process comprises the following steps:
a) reaction of styrene with isopropanol at elevated temperature to obtain 4-phenyl-2-methyl-2-butanol, and
b) heterogeneously catalyzed hydrogenation of 4-phenyl-2-methyl-2-butanol over a catalyst suitable for ring hydrogenation of aromatics.
