Lt. Eremenko et al., CUBANE DERIVATIVES - 2 - SYNTHESIS AND STRUCTURES OF SOME ESTERS OF 1,4-CUBANEDICARBOXYLIC ACID, Russian chemical bulletin, 47(3), 1998, pp. 441-446
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 eaters 3a, 3b, 3e, and 3f were est
ablished by X-ray diffraction analysis. The cubane framework of compou
nd 3b is somewhat distorted, whereas the C-C bond lengths and bond ang
les in the other compounds remain virtually ideal.
