the reaction of pentadienyllithium with [(η6-C6Me6)RuCl2]2 provides a nonselective reaction, which affords a mixture of isomeric η1-, η3-, and η5-coordinated pentadienyl complexes, [(η6-C6Me6)Ru(η5-CH2CHCHCHCH2)]Cl (2-Cl), [(η6-C6Me6)Ru(η3-CH2CHCHCHCH2)Cl] (5), and [(η6-C6Me6)Ru(η1-CH2CHCHCHCH2)Cl]2 (6); the reaction of 1,4-pentadiene and [(η6-C6Me6)RuCl2]2 in ethanolic carbonate similarly gives a mixture
用于阳离子钌(II)的合成一般方法η 5 -戊二烯基化合物由(η稳定6 -C 6我6)的Ru片段已经研制成功。戊二烯基化合物[(η 6 -C 6我6)的Ru η 5 -CH 2 C(R 2)CHC(R 4)CH(R 5)}] BF 4(R 2 = R 4 = R 5 = H,2 -BF 4; R 2,R 4 = H,R 5 = Me,3; R2,R 4 =我,R 5 = H,4)可以以良好的产率从不稳定双阳离子的反应来制备[(η 6 -C 6我6)的Ru(丙酮)3 ](BF 4)2(1)分别与1-三甲基甲硅烷基-2,4-戊二烯,1-三甲基甲硅烷基-2,4-己二烯和2,4-二甲基-1-三甲基甲锡烷基-2,4-戊二烯成对。以顺式和反式异构体的混合物的形式,以90%的收率分离出化合物3。与此相反,pentadienyllithium的反应与[(η 6 -C 6我6)的RuCl2 ] 2提供了一
