167693-07-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 167693-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,6,9 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 167693-07:
(8*1)+(7*6)+(6*7)+(5*6)+(4*9)+(3*3)+(2*0)+(1*7)=174
174 % 10 = 4
So 167693-07-4 is a valid CAS Registry Number.

Synthesis of DBpin using Earth-abundant metal catalysis

Cummins, Andrew W. M.,Docherty, Jamie H.,Li, Shuyang,Muilu, Tommi,Thomas, Stephen P.,Willcox, Dominic R.

, (2020)

The synthesis of DBpin was achieved using (EtBIP)CoCl2 or (tBuPNN)FeCl2 as pre-catalysts activated with NaOtBu. (EtBIP)CoCl2 was used as a pre-catalyst for the hydrogen isotope exchange of HBpin with D2, and (tBuPNN)FeCl2 for deuterogenolysis of B2pin2. The one-pot, tandem hydrogenolysis-hydroboration/deuterogenolysis-deuteroboration reaction of terminal alkenes could be catalysed by (tBuPNN)FeCl2 to give alkyl boronic esters.

Enantioselective Cobalt-Catalyzed Cascade Hydrosilylation and Hydroboration of Alkynes to Access Enantioenriched 1,1-Silylboryl Alkanes

Jin, Shengnan,Liu, Kang,Song, Qiuling,Wang, Shuai

supporting information, p. 13124 - 13134 (2021/09/03)

Enantioenriched 1,1-silylboryl alkanes possess silyl and boryl groups that are both connected to the same stereogenic carbon center at well-defined orientations. As these chiral multifunctionalized compounds potentially offer two synthetic handles, they are highly valued building blocks in asymmetric synthesis as well as medicinal chemistry. Despite the potential usefulness, efficient synthetic approaches for their preparation are scarce. Seeking to address this deficiency, an enantioselective cobalt-catalyzed hydrosilylation/hydroboration cascade of terminal alkynes has been realized. This protocol constitutes an impressive case of chemo-, regio-, and stereoselectivity wherein the two different hydrofunctionalization events are exquisitely controlled by a single set of metal catalyst and ligand, an operation which would usually require two separate catalytic systems. Downstream transformations of enantioenriched 1,1-silyboryl alkanes led to various valuable chiral compounds. Mechanistic studies suggest that the present reaction undergoes highly regioselective and stereocontrolled sequential hydrosilylation and hydroboration processes.

Copper-Photocatalyzed Hydroboration of Alkynes and Alkenes

supporting information, p. 14498 - 14503 (2021/05/21)

The photocatalytic hydroboration of alkenes and alkynes is reported. The use of newly-designed copper photocatalysts with B2Pin2 permits the formation a boryl radical, which is used for hydroboration of a large panel of alkenes and a

METHODS OF BORYLATION AND USES THEREOF

-

Page/Page column 35; 51-52, (2021/04/30)

The present invention relates, in general terms, to methods of borylation and uses thereof. In particular, the present invention provides a method of borylating an alkene compound by contacting the compound with a boron compound, a Fe pre-catalyst and a protic additive. The borylation occurs at a vicinal (β) position to an electron donating or electron withdrawing moiety of the compound.

Site-Fixed Hydroboration of Terminal and Internal Alkenes using BX3/iPr2NEt**

An unprecedented and general hydroboration of alkenes with BX3 (X=Br, Cl) as the boration reagent in the presence of iPr2NEt is reported. The addition of iPr2NEt not only suppresses alkene polymerizat

Chromium-Catalyzed Borylative Coupling of Aliphatic Bromides with Pinacolborane by Hydrogen Evolution

Fu, Aiping,Li, Chao,Luo, Meiming,Zeng, Xiaoming,Zhao, Lixing

supporting information, p. 2204 - 2208 (2021/06/28)

The chromium-catalyzed borylative coupling between aliphatic bromides and pinacolborane (HBpin) is described. This reaction was promoted by low-cost and bench-stable CrCl3as a precatalyst combined with 4,4′-di-tert-butyl-2,2′-dipyridyl and aluminum, presenting a rare example of using HBpin as a borane reagent by coupling with alkyl bromides in forming borylated alkanes. Mechanistic studies indicate that aluminum plays important roles in the formation of reactive Cr species and aliphatic radicals, which lead to (alkyl)Cr by reaction with HBpin to give the products.

Photoinduced NaI-Promoted Radical Borylation of Alkyl Halides and Pseudohalides

Wang, Chenglan,Zhou, Lu,Yang, Kai,Zhang, Feng,Song, Qiuling

A method for photoinduced NaI-promoted radical borylation of aliphatic halides and pseudohalides with bis(catecholato)diboron (B2cat2) as the boron source is introduced. The borylation reaction is operationally simple and shows high

Matteson Reaction under Flow Conditions: Iterative Homologations of Terpenes

Kuhwald, Conrad,Kirschning, Andreas

, p. 4300 - 4304 (2021/05/26)

The Matteson reaction is ideally suited for flow chemistry since it allows iterative homologation of boronate esters. The present study provides accurate data on reaction times of the individual steps of the Matteson reaction, which occurs in less than 10 s in total. The protocol allows terpenes to be (per-)homologated in a controlled manner to yield homo-, bishomo-, and trishomo-terpenols after oxidative workup. The new terpene alcohols are validated with respect to their olfactoric properties.

Electrochemical Borylation of Alkyl Halides: Fast, Scalable Access to Alkyl Boronic Esters

Cao, Yangmin,Hu, Ping,Huang, Cheng,Liu, Zhao,Lu, Qingquan,Ma, Wan,Peng, Pan,Qi, Xiaotian,Wang, Bingbing

supporting information, p. 12985 - 12991 (2021/09/03)

Herein, a fast, scalable, and transition-metal-free borylation of alkyl halides (X = I, Br, Cl) enabled by electroreduction is reported. This process provides an efficient and practical access to primary, secondary, and tertiary boronic esters at a high current. More than 70 examples, including the late-stage borylation of natural products and drug derivatives, are furnished at room temperature, thereby demonstrating the broad utility and functional-group tolerance of this protocol. Mechanistic studies disclosed that B2cat2 serves as both a reagent and a cathodic mediator, enabling electroreduction of difficult-to-reduce alkyl bromides or chlorides at a low potential.
