Summary

In the photochemical addition of bromine in nonpolar solvents, 2-butyne-1,4-diol, its diacetate, and 2,5-dimethyl-3-hexyne-2,5-diol form mainly cis-dibromides, whereas diphenylacetylene gives mainly the trans-addition product. Under these conditions the tendency for disubstituted acetylenes to undergo cis addition of bromine falls with increase in the size of the substituent.
