1，4-二(三甲基硅基)乙烯与过量锂在四氢呋喃中反应制得1，4-二锂硫代-1，1，4，4-四(三甲基硅基)丁烷，8加入无水二氯化锡的乙醚悬浮液中，在-100℃下，在0℃下搅拌1h，室温下搅拌20min，用溶剂代替己烷。对悬浮液进行过滤，得到暗红色的溶液。正己烷在-20℃下的再结晶
1, 4-Dilithio-1, 1, 4, 4-tetrakis (trimethylsilyl) butane, prepared in THF by the reaction of 1, 1-bis (trimethylsilyl) ethylene with excess lithium, 8 was added to a suspension of anhydrous tin dichloride in ether in a Schlenk tube at-100 C and thenstirred for 1 h at 0 C. After additional stirring for 20 min at room temperature, the solvent was substituted for hexane. Filtration of the suspension gave a dark-red solution. Recrystallization from hexane at-20
