  Rational synthesis of hexanuclear metallacycles by alkylation reactions of an S-bridged CoIIIPdIICoIII trinuclear complex containing non-binding thiolato groups

  摘要：

  The reaction of an S-bridged (CoPdCoIII)-Pd-III-Co-II trinuclear complex containing two non-bridging thiolato groups, [Pd(Co(aet)(3)}(2)](2+) (aet = 2-aminoethanethiolate), with o-dibromoxylene (o-xylBr(2)) in water produced a cyclic (Co4Pd2II)-Pd-III hexanuclear complex, [{Co2P-d(aet)(4)}(2)(o-L)(2)](8+) ([1](8+); o-L = o-bis(2-aminoethylthiomethyl)benzene), in which two (CoPdCoIII)-Pd-III-Co-II trinuclear units are linked by two o-xyl(2+) moieties through C-S bonds. A similar cyclic (Co4Pd2II)-Pd-III complex, [{Co2Pd(aet)(4))(2)(m-L)(2)](8+)([2](8+); m-L = m-bis(2-aminoethylthiomethyl)benzene), bearing a relatively large cavity that accommodates water molecule(s), was synthesized by the reaction of [Pd{Co(aet)(3)}(2)](2+) with m-dibromoxylene (m-xylBr(2)) in water. While [1](8+) afforded only the racemic (Delta(4)/Lambda(4)) isomer, both the racemic ([2a](8+); Delta(4)/Lambda(4)) and the meso ([2b](8+); Delta(2)Lambda(2)) isomers were formed for [2](8+). In addition, the meso [2b](8+) was found to exist as a mixture of two diastereomers, (Delta(S))(2)(Lambda(R))(2) and (Delta(S)Lambda(R))(Delta(R)Lambda(S)), which arise from the difference in chiral configurations (R and S) of asymmetric sulfide S atoms, while the racemic [1](8+) and [2a](8+) existed as a pair of enantiomers, (Delta(S))(4) and (Lambda(R))(4), which were optically resolved. The complexes obtained were characterized on the basis of electronic absorption, CD, and NMR spectroscopies, along with single crystal X-ray analyses. (c) 2006 Elsevier B.V. All rights reserved.
