The ortho, meta, and para isomers 4–6 of [6.6]cyclophanes with 2,5-diselenahex-3-ynebridges were synthesized by reacting the bis(selenocyanatomethyl)benzene derivatives 8a–8c with the lithium salt of trimethylsilylethyne to yield 9a–9c, deprotection of which afforded the bis(ethynylselenylmethyl)benzenes 10a–10c. The condensation of the bis-lithium salts of 10a–10c with 8a–8c yielded the target compounds
