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.
