The interaction of nickelocene with 3,6-di-tert-butyl-o-benzoquinone
摘要:
The interaction of nickelocene with 3,6-di-tert-butyl-o-benzoquinone in toluene gives new 18-electron complex (eta(5)-cyclopentadienyl)(eta(3)-{5,8-di-tert-butyl-3a,9a-dihydro-1H-cyclopenta(b)[1,4]benzodioxin-1-il})nickel(II) as the main product of hetero-Diels-Alder reaction. This process being carried out in THF solution is accompanied by ligands exchange and leads mainly to octahedral complex bis(3,6-di-tert-butyl-o-benzosemiquinonate)-bis(tetrahydrofuran)nickel(II).
