Addition of 1,2-dibromoacenaphthylene to Ni(COD)2/2L gives the oxidative-addition products trans-NiL2(Br)(2-bromoacenaphthylen-1-yl) (L = PEt3, PMe3). The intermediate π-complex Ni(PMe3)2(η2-1,2-dibromoacenaphthylene) is isolated at short reaction times for L = PMe3. An analogous complex, Pt(PEt3)2(η2-1,2-dibromoacenaphthylene), is formed in the reaction of Pt(PEt3)4 with 1,2-dibromoacenaphthylene
1,2- dibromoacenaphthylene成Ni(COD)的加成2 / 2L给出了氧化-加成产物的反式-NiL 2(BR)(2- bromoacenaphthylen -1-基)(L = PET 3,PME 3)。中间π络合物的Ni(PME 3)2(η 2 -1,2- dibromoacenaphthylene)在短的反应时间为L = PME分离3。类似的复合物,
铂(PET 3)2(η 2 -1,2- dibromoacenaphthylene),形成在
铂(PET的反应3)4与1,2- dibromoacenaphthylene和必须加热,以诱导氧化加成到顺-Pt(PEt 3)2(Br)(2-
