We successfully accomplished the synthesis, isolation and characterization of 1, 2-dialkynyldislenes containing various substituents. A closer investigation of their spectroscopic properties clearly showed a conjugation ofπ-electrons between the disilene and alkynyl moieties. Desilylation or degermylation reactions of trimethylsilylethynyl or trimethylgermylethynyl-substituted disilenes with methyllithium resulted in the formation of the corresponding lithium acetylide derivatives, which were subsequently protonated to yield 1, 2-dialkynyldislenes with terminal alkynyl groups. These disilenes are potentially useful synthons for the construction of novelπ-conjugated systems containing disilene units

我们成功地完成了含不同取代基的1,2 -二炔二烯的合成、分离和表征。对其光谱性质的进一步研究清楚地表明，二烯和炔基基团之间存在π-电子共轭。三甲基硅基乙炔或三甲基硅基乙炔取代二烯与甲基锂的脱硅或脱germyylation反应可生成相应的乙酰化锂衍生物，这些衍生物随后被质子化生成带有末端炔基的1,2 -二炔基二烯。这些二二烯是构建含有二二烯单元的新π共轭体系的潜在有用的合成物
