“…3 Until now, the favoured perception of the reaction scheme is based on radical mechanisms in which [Zn 2 Cp* 2 ] is formed by dimerization of the monovalent, radical fragments [Cp*Zn˙]. 4 The first reports on [Zn 2 Cp* 2 ] were mostly dealing with the structure and bonding situation of the Cp* stabilized Zn 2 molecule itself, recent studies also focus on the synthesis of new Zn 2 containing derivatives [Zn 2 R 2 ] (R ≠ Cp*) [4][5][6][7][8][9][10][11][12][13][14][15][16][17] as well as the reactivity of [Zn 2 Cp* 2 ] towards aryl or alkyl alcohols in the presence of stabilizing nitrogen donors. 18 In contrast to neutral organo Zn I compounds, the knowledge on related cationic species is still rather limited.…”

“…Second, the reductive coupling of Zn II species in the presence of stabilizing ligands L can lead to compounds with Zn-Zn bonds. [3][4][5][6][7][8][9][10][11] ] as the only product. Obviously, the nature of the deployed solvent is of major importance in the context of reaction control.…”

“…Interest in the chemistry of dizincocene and other Zn-Zn bonded compounds has been maintained in 2010. New examples include [(Tp Me2 )Zn-Zn(Tp Me2 )], 1 [(CH 2 {Ph 2 PQNPh} 2 )Zn-Zn(CH 2 {Ph 2 PQNPh} 2 )] and an example of a heteroleptic compound [Cp*Zn-Zn(CH 2 {Ph 2 PQNR} 2 )] (R = Ph, SiMe 3 , Ar), 2 all of which were synthesized from Cp*Zn-ZnCp*, A. The reactivity of A with Ar mes OH in the presence of 4-pyrrolidinopyridine afforded the first example of a Zn-Zn containing compound with an anionic oxygen donor ligand.…”

“…It was reported, however, that the tris(triazolyl)borate compounds, (Ttz tBu,Me )ZnR (R = Et, Me) co-crystallized with water and were stable towards oxygen. 5 In contrast, methylzinc amino alcoholates react with oxygen at low temperatures via a controlled insertion into a Zn-C bond to form the peroxide (1). 6 This unstable species decomposes to give a mixture of three oxygen containing zinc compounds composed of a hydroxide and two oxide aggregates.…”
