sterically demanding pentaarylcyclopentadienyl radical CpBIGt-Bu• (1; CpBIGt-Bu = Cp(4-t-Bu-Ph)5) reacts with group 2, group 13, and group 14 metal amalgams to form the following complexes of the type CpBIGt-Bu2M (M = Ca (3), Sr (4), Ba (5)), CpBIGt-BuM′ (M′ = Ga (6), In (7), Tl (8)) and CpBIGt-Bu2M′′ (M′′ = Sn (10), Pb (11)). In addition, metallocenes CpBIG2Mg (2), CpBIG2Hg (12), and CpBIG2Ge (9)
具有空间要求的五芳基环戊二烯基Cp BIG t -Bu •(1; Cp BIG t -Bu = Cp(4- t -Bu-Ph)5)与第2组,第13组和第14组金属汞齐反应形成以下配合物类型Cp BIG t -Bu 2 M(M = Ca(3),Sr(4),Ba(5)),Cp BIG t -Bu M'(M'= Ga(6),In(7), Tl(8))和Cp BIG t -Bu 2 M''(M''= Sn(10),Pb(11))。此外,茂金属Cp BIG 2 Mg(2),Cp BIG 2 Hg(12)和Cp BIG 2 Ge(9)在1与蒽镁(2)和元素汞(12)的反应中形成,并通过Cp BIG t -Bu K与GeCl 2 ·二恶烷之间的盐复分解反应(9)。发现6与(coe)Cr(CO)5(coe =顺式-环辛烯)反应形成Cp BIG吨-Bu GaCr(CO) 5( 13)。2 – 13通过元素分
