A series of dialkyne building blocks based on the dithia[3.3]paracyclophane unit have been synthesized in good yields. The electronic properties of these novel dialkynes can be tuned through a transannular substitution effect. These synthetically more accessible diethynyldithia[3.3]paracyclophanes are promising candidates for the building of relatively carbon rich molecular scaffolds.
