## Abstract The title compounds 8 and 1 have been synthesized in three steps each from 1,2‐dibromo[2.2]paracyclophan‐1‐ene (2) and 1,2,9,10‐tetrabromo[2.2]paracyclophane‐1,9‐diene (4), respectively. Copper‐mediated coupling of vinyl bromides 2 and 4 with methyl‐ and phenylmagnesium bromide gives su
