ABSTRACT:
Cyclohexanedione-(1,4)-tetramethyl diketal of the formula ##STR1## is obtained by catalytic hydrogenation of p-benzoquinone tetramethyl diketal in a basic medium, at a temperature of from about -10.degree. to +150.degree. C. The product gives cyclohexanedione-(1,4), on acid hydrolysis, which is a valuable starting product for various syntheses, for example for tetracyanoquinodimethane, a desired compound in the field of semiconductors.
Hydroquinone dimethyl ether, which is a valuable intermediate for the dyestuff preparation, is obtained from cyclohexanedione-(1,4)-tetramethyl diketal by catalytic dehydrogenation.
