YCl3, SmCl3, LuCl3, and YbI2 react with the lithium, sodium, and potassium salts of 1-(but-3-enyl)-2,3,4,5-tetramethylcyclopentadiene, yielding [(CH2CHCH2CH2C5Me4)2LnCl]2 (Ln = Y (3a), Sm (3b), Lu (3c)) and (CH2CHCH2CH2C5Me4)2Yb (6), respectively. The monomeric THF adducts (CH2CHCH2CH2C5Me4)2LnCl(THF) (Ln = Y (2a), Sm (2b)) crystallize from hexane. Li[C5Me4CH2CH2CH2CHCH2] reacts with SmCl3, yielding
YCl 3,SmCl 3,LuCl 3和YbI 2与1-(but-3-enyl)-2,3,4,5-tetramethylcyclopentadieneene的锂盐,钠盐和钾盐反应,生成[(CH 2 CHCH 2 CH 2 C 5 Me 4)2 LnCl] 2分别为(Ln = Y(3a),Sm(3b),Lu(3c))和(CH 2 CHCH 2 CH 2 C 5 Me 4)2 Yb(6)。单体THF加合物(CH 2CHCH 2 CH 2 C 5 Me 4)2 LnCl(THF)(Ln = Y(2a),Sm(2b))从己烷中结晶。Li [C 5 Me 4 CH 2 CH 2 CH 2 CH CH 2 ]与SmCl 3反应,得到(CH 2 CHCH 2 CH 2 CH 2 C 5 Me 4)2 SmCl(THF)(5b)。YCl 3,SmCl 3和LuCl的反应3具有1当量的M [C 5 Me 4
