The chemical behaviour of various alkyl-substituted, acyclic conjugated bisallenes in reactions involving polar intermediates and/or transition states has been investigated on a broad scale for the first time. The reactions studied include lithiation, reaction of the thus formed organolithium salts with various electrophiles (among others, allyl bromide, DMF and acetone), oxidation to cyclopentenones
首次大规模研究了各种烷基取代的无环共轭双丙二烯在涉及极性中间体和/或过渡态的反应中的化学行为。研究的反应包括锂化、由此形成的有机锂盐与各种亲电子试剂(其中包括烯丙基溴、DMF 和丙酮)的反应、氧化成环戊烯酮和环氧化物、卤化氢(HCl、HBr 加成)、卤化(Br(2) 和 I (2)加成),以及与氯磺酰基异氰酸酯的[2+2]环加成。所得加合物通过光谱和分析方法进行了充分表征;它们构成了进一步有机转化的有趣底物。
