Beryllium organoberyllium compounds

In addition to magnesium, there is an extensive chemistry of organoberyllium compounds. The alkyl compounds are obtained most conveniently by the reaction of beryllium chloride with a Grignard reagent. 

A33. D. A. Everest, The Chemistry of Beryllium. Elsevier, Amsterdam, 1964. Chapter 7, 20 pp. (37) deals with organoberyllium compounds. 

Beryllium with its marked tendency for involvement in covalent binding plays in a way an exceptional role within the Ila elements. Some material is available for chemical shifts and linewidths in organoberyllium compounds. These data have been collected in Table 3. As can be seen from the reference list,... 

A thermal reaction of NHC with silane has been uncovered and corresponds formally to a silicon insertion in the C-N bond of the carbene to form a diazasilinane (Scheme 2). ° The reaction is thought to proceed through a Si-H insertion of the NHC followed by an amide transfer and a second hydrogen shift. A similar ring expansion of NHC has been reported to proceed under beryllium activation in the presence of a silane yielding an organoberyllium compound. ...
