The bromine or iodine atom in the quinonoid ring devoid of +M substituent in the position neighboring to the halogen is replaced by acetylenic groups on treatment with CuI acetylides, prepared either beforehand or in situ, in a mixture of DMSO and CHCl3 in the presence of a Pd complex catalyst. A series of mono- and diacetylenic derivatives of 1,4-naphtho- and 1,4-benzoquinone were prepared.

A series of 2,3-diyne-1,4-naphthoquinone derivatives was synthesized from 2,3-dibromo1,4-naphthoquinone and various functionalized terminal alkynes using palladium-catalyzed Sonogashira cross-coupling reaction. The diynes were evaluated as potential cytotoxic agents against three tumor cell lines: human ovarian adenocarcinoma (OVCAR-8), human metastatic prostate cancer (PC-3M) and human bronchoalveolar lung carcinoma (NCI-H358M), presenting, in general, satisfactory results for inhibition of cell growth.
