Nickel-Catalyzed Stereoselective Diarylation of Alkenylarenes
Gao, Pin,Chen, Liang-An,Brown, M. Kevin
, p. 10653 - 10657 (2018)
A three-component coupling of aryl bromides, arylboron reagents, and alkenylarenes is presented. The method tolerates a variety of substitution patterns on all of the components. In particular, 1,2-disubstituted alkenylarenes are suitable and undergo highly diastereoselective diarylation.

Paragraph 0036-0037, (2020/07/04)
The present invention discloses a method for preparing a phenylboronic acid neopentyl glycol ester. A mixed nickel(II) complex with a formula of Ni[P(OR1)3][(R2NCH2CH2NR2)C]X2 is used as a catalyst. The method comprises: in the presence of potassium methoxide, efficiently catalyze a cross coupling reaction between a phenyl chloride and a bis(neopentyl glycolato)-diboron to prepare a phenylboronic acid neopentyl glycol ester. The invention provides the first embodiment of using a mixed nickel(II) complex with phosphonate ester and nitrogen heterocyclic carbene ancillary ligands to catalyze a cross coupling reaction.

Paragraph 0024; 0025, (2016/10/20)
The invention discloses a method for preparing arylboronic acid neopentyl glycol ester.The method includes the steps that a mixed-type nickel (II) complex with Ni(P(OR1)3)((R2NCH2CH2NR2)C)X2 as the chemical formula serves as a catalyst, and a cross coupling reaction of phenyl chlorine substitutes and bis(neopentyl glycolato) diboron is efficiently catalyzed in potassium methoxide to prepare the arylboronic acid neopentyl glycol ester.The method is the first case that the mixed-type nickel (II) complex catalyzes the cross coupling reaction with phosphite ester and n-heterocyclic carbine as auxiliary ligands.
Efficient metal-free photochemical borylation of aryl halides under batch and continuous-flow conditions

, p. 3676 - 3680 (2016/06/09)
A rapid, chemoselective and metal-free C-B bond-forming reaction of aryl iodides and bromides in aqueous solution at low temperatures was discovered. This reaction is amenable to batch and continuous-flow conditions and shows exceptional functional group tolerance and broad substrate scope regarding both the aryl halide and the borylating reagent. Initial mechanistic experiments indicated a photolytically generated aryl radical as the key intermediate.
