Yamamoto, Takeshi published the artcileBoryl-Directed, Ir-Catalyzed C(sp3)-H Borylation of Alkylboronic Acids Leading to Site-Selective Synthesis of Polyborylalkanes, Synthetic Route of 111562-32-4, the main research area is iridium catalyst borylation alkylboronic acid boryl directing group; chemoselective polyboryl alkane preparation.
Pyrazolylaniline serves as a temporary directing group attached to the boron atom of alkylboronic acids in Ir-catalyzed C(sp3)-H borylation. The reaction takes place at α-, β-, and γ-C-H bonds, giving polyborylated products including di-, tri-, tetra-, and even pentaborylalkanes. α-C-H borylation was generally found to be the preferred reaction of primary alkylboronic acid derivatives, whereas β- or γ-borylation also occurred if β- or γ-C-H bonds were located on the Me group.
Organic Letters published new progress about Boronic acids Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation). 111562-32-4 belongs to class pyrazoles-derivatives, name is 2-(1H-Pyrazol-3-yl)aniline, and the molecular formula is C9H9N3, Synthetic Route of 111562-32-4.
