  Synthesis and Solid-State Structure of Perfluorophenyl End-Capped Polyynes

  摘要：

  Five new supramolecular building blocks have been synthesized on the basis of polyynes end-capped with pentafluorophenyl groups, including three symmetrical (16, 17, 18) and two unsymmetrical polyynes (7 and 12). The solid-state behavior of these molecules based on the attractive electrostatic interactions of the phenyl and perfluorophenyl groups has been examined by X-ray crystallographic analysis of 7, 12, and 16.25.

  4-iminopyrimidines were efficiently prepared via copper-catalyzed three-component reactions of butadiynes, sulfonylazides, and hydrazides or imidamides. The reactions were regioselectively approached via the formation of a β-alkynyl-N-sulfonyl ketenimine intermediate which represented a new and effective 1,3-dielectrophilic equivalent in organic synthesis.

  Three diacetylene monomer model compounds with similar π-conjugation systems, 10-phenyl-5,7,9-decatriynyl N-phenylcarbamate (1), (E)-10-phenyldec-9-en-5,7-diynyl N-phenylcarbamate (2), and (E)-10-phenyldec-5-en-7,9-diynyl N-phenylcarbamate (3), were synthesized and their properties and solid-state polymerization were investigated. Based on the absorption spectra of the monomers, it was found that the conjugation effect of a double bond was different from that of a triple bond in solution. Monomers 1, 2, and 3 gave one, two, and five crystal forms, respectively, of which 1 and one of the crystal forms of 2 (2a) could be polymerized in the solid state. The conversions after γ-ray irradiation (1 MGy dose) were 53% and 20%, respectively. The longest-wavelength absorption maxima of the polymers prepared from 1 and 2a were 645 and 655 nm, respectively. The polymerizable crystals 1 and 2a were found to have layered monomer structures with spacing of 3.1–3.6 nm. Based on solid-state 13C NMR spectra, the polymerization sites of 1 were determined to be the 1,4- and 3,6-positions with respect to the phenyl ring, and that of 2a was determined to be the 3,6-position with respect to the phenyl ring.

  合成了三种具有相似π-共轭体系的二乙炔单体模型化合物，即10-苯基-5,7,9-十碳三炔基N-苯基氨基甲酸酯（1）、（E）-10-苯基-9-十碳烯-5,7-二炔基N-苯基氨基甲酸酯（2）和（E）-10-苯基-5-十碳烯-7,9-二炔基N-苯基氨基甲酸酯（3），并研究了它们的性质和固态聚合性。根据单体的吸收光谱，发现溶液中双键的共轭效应与三键不同。单体1、2和3分别呈现一种、两种和五种晶型，其中单体1和单体2的一种晶型（2a）可以在固态下聚合。经过γ射线辐照（剂量为1 MGy）后，转化率分别为53%和20%。由单体1和2a制备的聚合物的最长波长吸收最大值分别为645 nm和655 nm。可聚合的晶体1和2a被发现具有层状单体结构，间距为3.1-3.6 nm。根据固态13C NMR光谱，确定了单体1的聚合位点为苯环的1,4-和3,6-位，单体2a的聚合位点为苯环的3,6-位。
