The first successful catalytic borylation of unactivated aromatic C-N bonds of tertiary anilines without the preactivation or any directing groups is demonstrated. The reactivity of both N,N-dialkylarylamines and N-arylpyrroles were investigated systematically, and the targeted products were furnished in moderate to good yields. The DFT calculation results indicated that the catalytic cycle is furnished via a five-membered cyclic transition-state due to the steric hindrance of the Ni/NHC catalytic system.

Paragraph 0034; 0037, (2018/11/22)
PROBLEM TO BE SOLVED: To provide an economical and industrially advantageous method for obtaining an arylboronic acid alkylene diol ester of high purity, especially one having a remarkably low halogen content. SOLUTION: Provided is a method for producing a C5-25 arylboronic acid alkylene diol ester crystals, comprising: step A of producing a C5-25 aryl boronic acid alkylene diol ester by reacting a C3-20 arylboronic acid and a C2-5 alkylene diol in organic solvent; and step B of precipitating the C5-25 arylboronic acid alkylene diol ester obtained in step A in the reaction solution of the above step.

Rhodium-catalyzed borylation reactions of aryl and alkenyl pivalates, using a diboron reagent, via the cleavage of carbonoxygen bonds have been developed. The inert nature of the pivalate moiety enables relatively complex aryl boronates to be synthesized via the tandem cross-coupling of carbonhalogen and carbonoxygen bonds.
Nickel-catalyzed reductive and borylative cleavage of aromatic carbon-nitrogen bonds in N-aryl amides and carbamates

The nickel-catalyzed reaction of N-aryl amides with hydroborane or diboron reagents resulted in the formation of the corresponding reduction or borylation products, respectively. Mechanistic studies revealed that these reactions proceeded via the activation of the C(aryl)-N bonds of simple, electronically neutral substrates and did not require the presence of an ortho directing group.
