Lt. Eremenko et al., CUBANE DERIVATIVES .1. SYNTHESIS AND MOLECULAR-STRUCTURES OF THE ESTERS OF 1,4-CUBANEDICARBOXYLIC ACID, Russian chemical bulletin, 43(4), 1994, pp. 619-623
An effective method of esterification of 1,4-cubanedicarboxylic acid w
ith alkylsulfuric acids is proposed. The derivatives of alkanols with
substantially different pK(a) values are obtained in high yields. Mole
cular structures of the esters obtained are confirmed by various metho
ds. The X-ray study showed a remarkable effect of the nature of an alk
yl radical on the geometry of the cubane core.
