A dinucleating bis(β-diketiminate) ligand with a flexible bridge has been employed to synthesize zinc complexes. The ligand, abbreviated H2L (H2L = N-(4-((2-((4-((2,6-diisopropylphenyl)imino)pent-2-en-2-yl)amino)ethyl)imino)pent-2-en-2-yl)-2,6-diisopropylaniline), was deprotonated with ZnEt2 to afford [LZn2Et2] (1). Reactions of 1 with 2 equiv of BnOH and nBuOH, resp., gave access to [LZn2(OBn)2]·C6H14 (2·C6H14) and [LZn2(OnBu)2] (3). Treatment of 1 with 2 equiv of I2 in THF produced [LZn2I2(THF)2]·2THF (4·2THF). X-ray single-crystal diffraction analyses revealed that they are all heteroleptic bimetallic compounds with two metal centers being chelated by one ligand set. The structurally similar compounds 1 and 4·2THF possess approx. C2 symmetry, with two β-diketiminate units being arrayed in head-to-tail antiparallel mode. Thus, the mol. structures of 1 and 4·2THF exhibit a seesaw-like topol. The structures of 2·C6H14 and 3 are almost identical, in which two zinc atoms are shared by two ZnN2C3 six-membered rings, two Zn2ON2C2 seven-membered rings, and one Zn2O2 four-membered ring. Therefore, the metal cores of 2·C6H14 and 3 display a crownlike topol. All complexes are catalytically active for the borylation of aryl iodides with B2Pin2 (B2Pin2 = 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bis(1,3,2-dioxaborolane)). Complex 1 shows higher activity in comparison to 2, 3, and 4·2THF. The borylation reactions catalyzed by 1 could proceed under mild conditions and can be applied to a series of substrates with high functional group generality. This methodol. thus represents a novel use of β-diketiminate zinc complexes for C-I borylation. In addition to this study using 1-Iodo-2-methoxybenzene, there are many other studies that have used 1-Iodo-2-methoxybenzene(cas: 529-28-2Synthetic Route of C7H7IO) was used in this study.
1-Iodo-2-methoxybenzene(cas: 529-28-2) participates in palladium catalyzed enantioselective Heck arylation of 2,3-dihydrofuran in the presence of chiral ionic liquids containing L-prolinate and L-lactate anions and non-chiral quaternary ammonium cations.Synthetic Route of C7H7IO
