Abstract:
In the title compound, C(21)H(30)O(6), the three acet-oxy groups are essentially planar with their normals rotated by -57.75 (4), -62.36 (4) and 63.36 (4)° from the normal to the mean plane of the C(6) ring. The arrangement of carbonyl groups around the ring is of two groups 'up' and one 'down', and the propeller-style arrangement of substituent groups is spoiled with the plane of the 'down' group twisted in the opposite direction; all the C(ring)-O-C-CMe(3 )conformations are trans. In the crystal, aromatic π-π stacking occurs [centroid-centroid separation = 3.320 (1) Å]; the other main inter-molecular inter-action is a C-H⋯π-ring contact on the opposing side from the overlapped ring pairing; there are no short C-H⋯O contacts.

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
