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.
在含有邻卤位置无+M取代基的醌环中,溴或碘原子在铜炔化物(事先制备或原位制备)、DMSO和CHCl3混合物中,在Pd配合物催化剂的存在下,被乙炔基团取代。制备了一系列的单乙炔和双乙炔衍生物,包括1,4-萘醌和1,4-苯醌。
