2-t-Alkylbuta-1,3-dienes were synthesized by the successive reaction of dialkylboranes, derived from tetrasubstituted ethenes and borane in tetrahydrofuran, with 1,4-dichlorobut-2-yne and methyl-lithium; 2-alkylthiobuta-1,3-dienes were synthesized by a similar reaction using alkylthiomagnesium bromides instead of methyl-lithium.
在四氢呋喃中,由四取代乙烯和硼烷衍生的二烷基硼烷与1,4-二氯丁-2-炔和甲基锂的连续反应合成了2-t-Alkylbuta-1,3-dienes。使用烷硫基溴化镁代替甲基锂,通过类似的反应合成了2-烷硫基丁-1,3-二烯。
