Here, we report the reaction between N‐phenyl‐o‐phenylenediamine and pyrrole‐2‐carboxaldehyde to afford the N‐phenyl‐o‐phenyl‐enediiminopyrrole ligand {L‐H2} in quantitative yield. A one‐pot reaction between {L‐H2} and diethylzinc (ZnEt₂) in a 2:1 ratio afforded the homoleptic zinc metal complex [{L‐H}₂Zn] (1). The solid‐state structures of ligand {L‐H2} and zinc complex 1 were confirmed using X‐ray crystallography. Further, complex 1 was used for chemoselective hydroboration of aldehydes and ketones in the presence of pinacolborane (HBpin) at ambient temperature to produce the corresponding boronate esters in high yield.

HBpin存在下同质锌催化醛和酮的硼氢化

在此，我们报告了N-苯基-邻-苯二胺与吡咯-2-甲醛之间的反应，以定量产率提供了N-苯基-邻-苯基-二烯丙基氨基吡咯配体{ L-H2 }。{ L-H2 }与二乙基锌（ZnEt ₂）之间以2：1的比例进行一锅法反应，得到均化的锌金属络合物[ {L-H} ₂ Zn ]（1）。X射线晶体学证实了配体{ L-H2 }和锌络合物1的固态结构。此外，复合物1 在环境温度下存在频哪醇硼烷（HBpin）的条件下，将其用于醛和酮的化学选择性氢硼化，以高产率生产相应的硼酸酯。
