Synthetic routes towards tetraethynylallene (4), a perethynylated modular entity for the construction of three-dimensional all-carbon networks and all-carbon backbone polymers with a stepladder or helical structure, are presented. They comprise propargylic rearrangements, cyclopropanations with carbenes, Peterson and Wittig-type olefinations, and alkylations of ketones with α-bromovinyl anions.
合成四乙炔基烯(4)的路线被提出,这是一种用于构建三维全碳网络和具有阶梯或螺旋结构的全碳骨干聚合物的全乙炔基模块实体。这些路线包括丙炔重排、与卡宾的环丙烷化、Peterson和Wittig型烯化以及酮与α-溴乙烯阴离子的烷基化。
