Аннотация:New esters of 1,4-cubanedicarboxylic acid, 1,4-(ROCO)(2)C8H6 (R = Et (3a), Pr (3b), CMe3 (3c), C6H13 (3d), CH2CF3 (3e), or CH(CF3)(2) (3f)) were synthesized. The structures of esters 3a, 3b, 3e, and 3f were established by X-ray diffraction analysis. The cubane framework of compound 3b is somewhat distorted, whereas the C-C bond lengths and bond angles in the other compounds remain virtually ideal.
