In 2018,Lee, Yeosan; Park, Jinyoung; Cho, Seung Hwan published 《Generation and Application of (Diborylmethyl)zinc(II) Species: Access to Enantioenriched gem-Diborylalkanes by an Asymmetric Allylic Substitution》.Angewandte Chemie, International Edition published the findings.Name: Bis[(pinacolato)boryl]methane The information in the text is summarized as follows:
Authors report the successful generation of (diborylmethyl)zinc(II) species by transmetalation between isolable (diborylmethyl)lithium and zinc(II) halide (X = Br, Cl) and their application in the synthesis of enantioenriched gem-diborylalkanes bearing a stereogenic center at the β-position of the diboryl groups by an asym. allylic substitution reaction. The reaction has a broad substrate scope, and various enantioenriched gem-diborylalkanes can be obtained in good yields with excellent enantioselectivity. Further elaboration of the enantioenriched gem-diborylalkanes provides access to a diverse set of valuable chiral building blocks. In the experiment, the researchers used Bis[(pinacolato)boryl]methane(cas: 78782-17-9Name: Bis[(pinacolato)boryl]methane)
Bis[(pinacolato)boryl]methane(cas: 78782-17-9) belongs to organoboron compounds.Name: Bis[(pinacolato)boryl]methane Organoboron compounds have been a cornerstone of synthetic transformations for decades. Areas such as boron-containing catalysts, metalate chemistry, photoredox methods, and boryl anions have brought significant new developments in understanding and provided new reactivity upon.
