本文通过对特丁基杯[4]芳烃的酚羟基烷基化和苯环特丁基位上的IPSO-硝化制备了一系列对硝基杯[4]芳烃烷基醚,烷基分别是n-C_4H_9(3a)、n-C_8H_(17)(3b)、n-C_(12)H_(25)(3c)和n-C_(16)H_(33)(3d)。~1H NMR表明所有新的杯[4]芳烃都具有锥形(cone)构象。
In this paper, a series of p-nitro-calix [4] arene alkyl ethers were prepared by alkylolation of phenolic hydroxyl groups of t-butyl calix [4] arene and IPSO- (3a), n-C_8H_ (17) (3b), n_C_ (12) H_ (25) (3c) and n_C_ (16) H_ (33) (3d). ~ 1H NMR indicated that all new calix [4] arenes had a cone conformation.
