《Cu-catalyzed C-C bond formation of vinylidene cyclopropanes with carbon nucleophilesã€?was written by Chen, Jichao; Gao, Shang; Chen, Ming. Synthetic Route of C13H26B2O4This research focused onvinylidene cyclopropane alkynylboronate regioselective nucleophilic addition reaction; dialkynyl ester preparation. The article conveys some information:

The development of Cu-catalyzed addition of carbon nucleophiles to vinylidene cyclopropanes was reported. The reactions with 1,1-bisborylmethane provided homopropargylic boronate products by forming a C-C bond at the terminal carbon atom of the allene moiety of vinylidene cyclopropanes. Alkynyl boronates are also suitable nucleophile precursors in reactions with vinylidene cyclopropanes, and skipped diynes were obtained in high yields. In addition, the Cu-enolate generated from the initial addition of nucleophilic copper species to vinylidene cyclopropanes can be intercepted by an external electrophile. As such, vinylidene cyclopropane serves as a linchpin to connect a nucleophile and an electrophile by forming two carbon-carbon bonds sequentially.

The article was titled 《Copper-Catalyzed Electrophilic Amination of gem-Diborylalkanes with Hydroxylamines Providing α-Aminoboronic Acid Derivativesã€? The information in the text is summarized as follows:

A copper-catalyzed electrophilic amination of gem-diborylalkanes with hydroxylamines has been developed. The key to its success is the use of the Me3Si-modified 1,2-bis(diphenylphosphino)benzene ligand. Addnl., the reactivity of neopentylglycol derivatives compared to that of commonly used pinacol-derived ones is found to be higher, particularly in the case of relatively sterically congested substrates. The copper catalysis presented here enables the first successful catalytic carbon-heteroatom bond forming reaction of gem-diborylalkanes to form the corresponding α-aminoboronic acid derivatives, which are of great interest in medicinal and pharmaceutical chem.

And the article was published in Chemical Science in 2019. Recommanded Product: Bis[(pinacolato)boryl]methane The author mentioned the following in the article:

Acylboronates represent a very intriguing and rare class of organoboronates. Synthesis of these compounds from readily available substrates under mild conditions and access to novel classes of acylborons has been challenging. Authors report a novel and concise route to various MIDA acylboronates from terminal alkynes/alkenes or vinyl boronic esters using unsym. geminal diborylalkanes as key intermediates. The high modularity and mild conditions of this strategy allowed a facile access to acylboronates possessing aliphatic, aromatic as well as the rarer heteroaromatic, alkynyl and α,β-unsaturated scaffolds. To the best of their knowledge, this is the first report of chemoselective oxidation of geminal diborons as well as synthesis of an α,β-unsaturated acylboronate.

《Chemodivergent transformations of amides using gem-diborylalkanes as pro-nucleophilesã€?was published in Nature Communications in 2020. These research results belong to Sun, Wei; Wang, Lu; Hu, Yue; Wu, Xudong; Xia, Chungu; Liu, Chao. Formula: C13H26B2O4 The article mentions the following:

A chemodivergent transformation of primary, secondary and tertiary amides by using 1,1-diborylalkanes as pro-nucleophiles was disclosed. In general, selective B-O elimination occurred for primary, secondary amides and tertiary lactams to generated enamine intermediate, while tertiary amides undergo B-N elimination to generated enolate intermediate. Various in-situ electrophilic trapping of those intermediates allowed the chemoselective synthesis of α-functionalized ketones, β-aminoketones, enamides, β-ketoamides, γ-aminoketones and cyclic amines from primary, secondary, tertiary amides and lactams. The key for these transformations was the enolization effect after the addition of α-boryl carbanion to amides.
