1242069-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1242069-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,0,6 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1242069-40:
(9*1)+(8*2)+(7*4)+(6*2)+(5*0)+(4*6)+(3*9)+(2*4)+(1*0)=124
124 % 10 = 4
So 1242069-40-4 is a valid CAS Registry Number.

2-[(Neopentyl glycolato)boryl]phenyl Triflates and Halides for Fluoride Ion-Mediated Generation of Functionalized Benzynes

Ikawa, Takashi,Yamamoto, Rika,Takagi, Akira,Ito, Toyohiro,Shimizu, Kazunori,Goto, Masahiko,Hamashima, Yoshitaka,Akai, Shuji

, p. 2287 - 2300 (2015/07/27)

2-[(Neopentyl glycolato)boryl]phenyl trifluoromethanesulfonates (triflates) and halides have been developed as new benzyne precursors, which generate benzynes at 120°C in the presence of a fluoride ion. There are two major features of these types of precu

On the use of 2-(trimethylsilyl)iodobenzene as a benzyne precursor

scheme or table, p. 6608 - 6610 (2011/01/12)

A mild method for the generation of benzynes from 2-(trimethylsilyl) iodobenzene derivatives is reported. The employment of silver fluoride in conjunction with caesium fluoride is key for promoting useful levels of elimination and providing benzyne derived products in good yields. Moreover, the substrates are accessed by a novel alkynyl iodide cycloaddition.

An alkynylboronate cycloaddition strategy to functionalised benzyne derivatives

supporting information; experimental part, p. 5154 - 5156 (2010/10/19)

A new approach to benzyne precursors has been developed that involves the [4+2] cycloaddition of trimethylsilyl alkynylboronates with 2-pyrones, followed by oxidation and trifluoromethylsulfonylation of the boronate moiety. The Royal Society of Chemistry
