Derived from the well known, Encyclopedia of Reagents for natural Synthesis (EROS), the comparable editors have created a brand new guide which makes a speciality of chiral reagents utilized in uneven synthesis and is designed for the chemist on the bench. This new guide follows an analogous structure because the Encyclopedia, together with an advent and an alphabetical association of the reagents.

Solvent coordination as a rule decreases the reactivity of Ln–R bonds by depolarization, steric saturation, and competition reactions. g. HMPA coordination [244]). g. OCPh2, OPPh3, TMEDA) [Eq. (32)] [245,246] and strongly donating ligands such as acetonitrile or pyridine were shown to act as denucleating agents in cyclopentadienyl and alkoxide chemistry [Eq. (33)] [20,247]. Substituted imidazol-2-ylidenes, carbene-type ligands, form strong adduct complexes with Ln(II) and Ln(III) metal centers as indicated by THF displacement [Eq.

These compounds can be of relevance in Lewis acid catalysis where their activity is directed by the formation of Lewis acid (catalyst)/base (substrate) pairs [229]. Hence, metal–ligand bond disruption and formation processes are pushed into the background. Linked cyclopentadienyl-carborane ligands form mononuclear commo (sandwiched) metallacarborane complexes [230]. Highly functionalized podate ligands such as triamidoamine (“azatrane”) [231] and tribenzyltrifluoroacetoacetate [232] produce formally 4- and 6-coordinated complexes, respectively (Fig.
