Duroquinone is the organic compound with the formula C4(CH3)4O2. It is related to 1,4-benzoquinone by replacement of four H centres with methyl (Me) groups. The C10O2 core of this molecule is planar with two pairs of C=O and C=C bonds.[1]

The compound is produced via nitration of durene (1,2,4,5-tetramethylbenzene) followed reduction to the diamine and then oxidation.[2]

A derived organoiron compound (η22-C4(CH3)4O2)Fe(CO)3 is obtained by the carbonylation of 2-butyne in the presence of iron pentacarbonyl.[3]

The molecule has been mentioned in the popular press as a component of a "nano brain".[4]
