摘要 : The reaction of [Pt- (CH_2COMe)(Ph)(cod)](cod=1,5-cy- clooctadiene)with(ArCH_2NH_2CH_2- C_6H_4COOH)~+(PF_6)~-(Ar=4-tBuC_6H_4 or 9-anthryl)in the presence of cyclic oligoethers such as dibenzo[24]crown-8 (DB24C8)and dicyclohexano[2... 展开 The reaction of [Pt- (CH_2COMe)(Ph)(cod)](cod=1,5-cy- clooctadiene)with(ArCH_2NH_2CH_2- C_6H_4COOH)~+(PF_6)~-(Ar=4-tBuC_6H_4 or 9-anthryl)in the presence of cyclic oligoethers such as dibenzo[24]crown-8 (DB24C8)and dicyclohexano[24]- crown-8 (DC24C8) produces((ce)[ArCH_2NH_2CH_2C_6H_4COOPt(Ph)-(cod)])~+(PF_6)~-(ce=DB24C8 or DC24C8,Ar=4-tBuC_6H_4 or 9-anthryl)with interlocked structures.FABMS and NMR spectra of a solution of these compounds indicate that the Pt complexes with a secondary ammonium group and DB24C8(or DC24C8)make up the axis and cyclic components,respectively.Temperature-dependent ~1H NMR spectra of a solution of {(DB24C8)[4-tBuC_6H_4CH_2NH_2CH_2-C_6H_4COOPt(Ph)(cod)]}~+(PF_6)~-(((DB24C8)[4-H])~+(PF_6)~-)show equilibration with free DB24C8 and the axis component.The addition of DB24C8 to a solution of {(DC24C8)[4-H])~+(PF_6)~-causes partial exchange of the macrocyclic component of the interlocked molecules,giving a mixture of {(DC24C8)[4-H]}~+(PF+6)~-,{(DB24C8)-[4-H])~+(PF_6)~-,and free macrocyclic compounds.Thereactionof 3,5-Me_2C_6H_3COCl with {(DB24C8)[4-H]}~+(PF_6)affords the organic rotaxane((DB24C8)(4-tBuC_6H_4CH_2NH_2CH_2-C_6H_4COOCOC_6H_3Me_2-3,5)}~+(PF_6)~-through C-O bond formation between the aroyl group and the carboxylate ligand of the axis component.The addition of 2,2'-bipyridine(bpy)to a solution of {(DB24C8)[4-H]}~+(PF_6)~-induces the degradation of the interlocked structure to form a complex with trigonal bipyramidal coordination,[Pt(Ph)-(bpy)(cod)]~+(PF_6)~_,whereas the reaction of bpy with [Pt(OCOC_6H_4Me-4)(Ph)(cod)] produces the square-planar complex [Pt(OCOC_6H_4Me-4)(Ph)(bpy)]. 收起
