Organometallic chemistry is generally considered the key to homogeneous catalysis, which,
although a century old, is still today a very dynamic discipline. 1 The past decade has seen …

Despite the routine employment of Grignard reagents and Hauser bases as stoichiometric
carbanion reagents in organic and inorganic synthesis, a defined reaction chemistry …

In sharp contrast to the use of conventional magnesium‐based Grignard reagents (R− MgX),
the application of calcium‐based heavy Grignard reagents (R− CaX) in organic synthesis …

Early Main Group Metal Catalysis gives a comprehensive overview of catalytic reactions in
the presence of group 1 and group 2 metals. Chapters are ordered to reaction type, contain …

The group 2 alkaline earth metals calcium (Ca), strontium (Sr), and barium (Ba) are among
the most common elements on Earth, abundant in both the sea and the Earth's crust …

Catalytic asymmetric 1, 4-addition and [3+ 2] cycloaddition reactions using chiral calcium
species prepared from calcium isopropoxide and chiral bisoxazoline ligands have been …

Within the general area of early main group metal chemistry, the controlled synthesis of well-
defined metal hydride complexes is a rapidly developing research field. As group 1 and 2 …

The development of bulky monodentate alkoxide, chalcogenolate (ER, E= S, Se or Te),
amide, pnictide (ER2= N, P, As), alkyl, aryl and silyl ligands is briefly surveyed. These …

We report here reactions between the N-adamantyliminopyrolyl ligand 2-(AdNCH)–
C4H3NH (L–H) and alkali metal hexamethyldisilazides [MN (SiMe3) 2](M= Li, Na and K) to …
