Organoberyllium Halides

Behavior of Lewis Bases toward Diphenylberyllium

“…In contrast to the ubiquity of organomagnesium reagents, organoberyllium chemistry is relatively unexplored due, at least in part, to the perceived toxicity of this element. − Indeed, although organoberyllium complexes were prepared as early as the 1920s, − the field has subsequently been relatively devoid of methodical, fundamental beryllium research. Recently, there has been renewed interest in the organometallic chemistry of beryllium, driven by a desire to understand the biotoxicity mechanisms of this element and exploit its unique electronic properties for chemical transformations. − Within the past five years, the first compounds containing formally zero- and monovalent beryllium centers, in addition to the first BeC and BeN bonds have all been reported. − …”

A study of highly crystalline novel beryllium oxide film using atomic layer deposition

“…To grow a thin BeO film, precursor (Be(CH 3 ) 2 ) was synthesized from BeCl 2 by Grignard metathesis [11] and subsequently utilized for the first time as an ALD precursor. Methyl magnesium bromide (CH 3 MgBr, 2.5 M in diethyl ether (Et 2 O)) was added in drops over 10 min to a rapidly stirred solution of BeCl 2 in anhydrous Et 2 O cooled to À30 1C.…”

A Preference for Heterolepticity ‐ Schlenk Type Equilibria in Organometallic Beryllium Systems

“…[14] However, reports on the formation of BeEtCl in ethereal solutions of BeEt 2 and BeCl 2 , [15] and other compounds of the type BeRX (R = Et, n Bu, Ph; X = Br, I) have been reported in Et 2 O in the 1920s. [16] Studies on ligand distribution and exchange reactions on these systems, which were performed in the 1960s give conflicting results. An investigation of the isotope scrambling in mixtures of 7 BeBr 2 + 9 BePh 2 found no evidence for ligand exchange.…”

“…It has been known for a century that in contrast to magnesium, beryllium metal does not directly react with alkyl‐ or arylhalides [14] . However, reports on the formation of BeEtCl in ethereal solutions of BeEt 2 and BeCl 2 , [15] and other compounds of the type BeR X (R=Et, n Bu, Ph; X =Br, I) have been reported in Et 2 O in the 1920s [16] . Studies on ligand distribution and exchange reactions on these systems, which were performed in the 1960s give conflicting results.…”
