They do exist after all : Molecular [La(AlEt 4 ) 3 ] of high purity can be obtained from the reaction of [La(NMe 2 ) 3 (LiCl) 3 ] with excess triethylaluminum. Although kinetically labile—the title complex decomposes gradually through β‐H abstraction and release of ethane—alkane elimination reactions are feasible, as shown for the synthesis of metallocene complex [(C 5 Me 5 ) 2 La(AlEt 4 )].
