Zinc β-diketiminates containing the N, N′-chelating ligand [{N (SiMe3) C (Ph)} 2CH]−(≡ LL−)[Zn (LL)(μ-Cl)] 2 (1) and [ZnEt (LL) thf](2) were prepared from 2ZnCl2+ [Li (LL)] 2 and ZnEt2+ H (LL), respectively. The new phenols 2-(NR-piperazinyl-N′-methyl)-4, 6-di-tert- butylphenol [R= Ph (3a), Me (3b)] and 2, 2-[μ-N, N′-piperazindiyldimethyl]-bis (4, 6-di-tert- butylphenol)(4) were obtained from 2, 4-tBu2C6H3OH,(CH2O) n and the appropriate ...
