The synthesis of seven ethynyl[2.2]paracyclophanes is described. The five diethynyl derivatives 4,5-diethynyl[2.2]paracyclophane (12), pseudo-gem- (13), pseudo-ortho- (14), pseudo-meta- (15), and pseudo-para-diethynyl[2.2]paracyclophane (16), the tetraethynyl compound 4,7,13,16-tetraethynyl[2.2]paracyclophane (17), and for comparison the mono-ethynylated hydrocarbon 4-ethynyl[2.2]paracyclophane (11) have been prepared. The structures of these new building blocks for carbon rich systems were determined by the usual analytical and spectroscopic methods.
本文介绍了七种乙炔基[2.2]对二环烷的合成。五种二乙炔基衍生物 4,5-二乙炔基[2.2]对二环乙烷 (12)、假庚烷 (13)、假正庚烷 (14)、假甲烷 (15) 和假对二乙炔基[2.2]paracyclophane (16)、四乙炔化合物 4,7,13,16-四乙炔基[2.2]paracyclophane (17),以及单乙炔化碳氢化合物 4-乙炔基[2.2]paracyclophane (11)。这些富碳体系新构件的结构是通过常用的分析和光谱方法确定的。
