“…The narrow view of solvents in the 1960s is particularly striking when it is realized that Gilman was examining lanthanum reactions in Et 2 O as early as 1945, and Wilkinson used tetrahydrofuran (THF) in 1954 to make the first cyclopentadienyl rare-earth metal complexes, (C 5 H 5 ) 3 Ln, where Ln = Sc, Y, La, Ce, Pr, Nd, Sm, and Gd, eq …”

Formulating insightful questions and experiments is crucial to the advancement of science. The purpose of this Perspective is to encourage scientists in all areas of chemistry to ask more “What if?” questions: What if we tried this experiment? What if we used these conditions? What if that idea is not correct? To stimulate this thinking, a retrospective analysis of a specific field, in this case rare-earth metal chemistry, is presented that describes the “What if?” questions that could have and should have been asked earlier based on our current knowledge. The goal is to provide scientists with a historical perspective of discovery that exemplifies how previous views in chemistry were often narrowed by predominant beliefs in principles that were incorrect. The same situation is likely to exist today, but we do not realize the limitations! Hopefully, this analysis can be used as a springboard for posing important “What if?” questions that should be asked right now in every area of chemical research.

“… 177 The first reaction of an RE with an organomercurial reagent was reported in 1945 by Gilman and Jones, who reacted La metal with HgPh 2 though they were not able to identify the reactivity products. 178 Broadly speaking, these methodologies can be divided into two categories: (1) redox transmetalation (RT) reactions and (2) redox transmetalation combined with ligand exchange, also termed redox transmetalation protonolysis or protolysis (RTP) ( Scheme 25 ). 12 Though initially developed for classic divalent Lns (Yb and Eu), RT and RTP reactions can also be used for the synthesis of trivalent RE derivatives.…”

The number of rare earth (RE) starting materials used in synthesis is staggering, ranging from simple binary metal-halide salts to borohydrides and “designer reagents” such as alkyl and organoaluminate complexes. This review collates the most important starting materials used in RE synthetic chemistry, including essential information on their preparations and uses in modern synthetic methodologies. The review is divided by starting material category and supporting ligands ( i.e. , metals as synthetic precursors, halides, borohydrides, nitrogen donors, oxygen donors, triflates, and organometallic reagents), and in each section relevant synthetic methodologies and applications are discussed.
