摘要/Abstract
将C5H5CR1R2CH2CH CH2[R1=R2=CH3(1);R1=CH3,R2=C3H7(2);R1=CH3,R2=C4H9(3);R1,R2=(CH2)5(4);R1=CH3,R2=C6H5(5)]与Ru3(CO)12在二甲苯中加热回流,合成了5个新的双核配合物[(η5-C5H4CR1R2CH CHCH3)2Ru2(CO)4][R1=R2=CH3(6);R1=CH3,R2=C3H7(7);R1=CH3,R2=C4H9(8);R1,R2=(CH2)5(9);R1=CH3,R2=C6H5(10)].通过元素分析、IR,1HNMR对其结构进行了表征.结果表明:产物中侧链烯丙基部位的双键发生了迁移,并没有与金属配位.对烯烃异构化反应可能的机理进行了探讨.
The ligands C5H5CR1R2CH2CH CH2 [ R1= R2= CH3 (1);R1= CH3,R2= C3H7(2);R1= CH3,R2= C4H9(3);R1,R2 = (CH2) 5(4);R1= CH3,R2= C6H5 (5) ] reacted with Ru3(CO) 12 in ref luxing xylene to give corresponding five new diruthenium metal carbonyl complexes [ (&eta5- C5H4CR1R2CH CHCH3 ) 2Ru2(CO)4] [ R1= R2= CH3(6);R1= CH3,R2= C3H7(7);R1 = CH3,R2= C4H9(8);R1,R2 = (CH2)5(9);R1= CH3,R2 = C6H5 (10) ],respectively.The five new complexes were characterized by Elemental analysis,IR spectra,1HNMR.Double bound isomerization complexes were obtained.It showed that double bond was not coordinated with the ruthenium atom.The possible mechanism for the olef in isomerization w as discussed.
