Allylzinc bromide reacts with lithium chloroacetylenide to give 4-allyl-4-methylhepta-1,6-diene in good yield. The reaction of allylzinc bromide with acetylene, prop-1-ynylmagnesium bromide and 3-bromoprop-1-yne resulted in the synthesis of 4-methylhepta-1,6-diene, 4,4-dimethylhepta-1,6-diene and 1,1-diallylcyclopropane respectively. These symmetrical polyenes were oxidized by MCPBA to yield the corresponding epoxides (the molar ratio of the reactants determined which epoxide formed).
Allylzinc溴化物与锂氯乙炔化物反应,以高产率生成4-烯丙基-4-甲基庚-1,6-二烯。Allylzinc溴化物与乙炔、丙炔基镁溴化物和3-溴丙炔的反应分别合成了4-甲基庚-1,6-二烯、4,4-二甲基庚-1,6-二烯和1,1-二烯丙基环丙烷。这些对称的聚烯经过MCPBA氧化生成相应的环氧化物(反应物摩尔比决定了生成哪种环氧化物)。
