摘要

以2,7-二羟基萘为起始原料, 经与8-(对甲苯磺酰氧基)-3,6-二氧-1-辛醇醚化, 再与对甲苯磺酰氯酯化得7, 7最后与2,7-二羟基萘在碳酸铯为碱作用下得基于2,7-二羟基萘基块新型的冠醚, 三步总收率为35%. 利用单晶X衍射研究其结构, 晶体为三斜晶系, P-1空间群, a＝8.165(3) Å, b＝13.435(4) Å, c＝14.083(3) Å, γ＝64.11(2)°, β＝80.40(3)°, γ＝88.19(3)°, V＝1368.9(7) Å3, Z＝2, Dc＝1.331 g/cm3, λ＝0.071070 nm, μ(Mo Kα)＝1.331 mm-1, Mr＝353.22, F(000)＝584. 在1的晶体结构中, 两个萘基块通过二缩三乙二醇醚键相连形成1个二萘并[30]-冠-8大环结构, 空腔大小为8.2 Å×12.0 Å, 分子呈Z型结构. 通过核磁研究了主体分子1对联吡啶盐在溶液中的相互络合作用.

Abstract

A Novel naphthalene-based crown ether has been synthesized by the etherification of 2,7-dihydroxynaphthalene with 8-tosyloxy-3,6-dioxaoctanol in the presence of K2CO3, followed by reaction with p-toluenesufonyl chloride to give 7. Compound 7 was further reacted with 2,7-dihydroxynaphthalene in the presence of cesium carbonate to give 1 in 38% total yield. Its crystal structure was determined by X-ray diffraction method. The crystal is of triclinic, space group P-1 with a＝ 8.165(3) Å, b＝13.435(4) Å, c＝14.083(3) Å, α＝64.11(2)°, β＝80.40(3)°, γ＝88.19(3)°, V＝1368.9(7) Å3, Z＝2, Dc＝1.331 g/cm3, λ＝0.071070 nm, μ(Mo Kα)＝1.331 mm-1, Mr＝353.22, F(000)＝584. The crystal structure of 1 shows that two napthalene units are linked two tri(ethylene glycol) bridges to form dinapthalzo[30]crown-8 cavity and one Z-like central cavity with size of ca. 8.2 Å×12.0 Å. The host 4 was proved to be a efficient host for the complexation with paraquat derivatives in solution by 1H NMR.

Key words： crown ethers; synthesis; crystal structure; complexation; paraquat derivatives
