Zinc, bis(bromomethyl)-, also known as dibromomethylzinc or Zn(CH2Br)2, is an organozinc compound that serves as a reagent in organic synthesis. It is a colorless, highly reactive, and moisture-sensitive solid, which is typically generated in situ and used immediately to avoid decomposition. Zinc, bis(bromomethyl)- is a valuable building block for the formation of carbon-carbon bonds, particularly in the Negishi coupling reaction, where it acts as a nucleophile to couple with various organic electrophiles. Due to its high reactivity, it is crucial to handle it under an inert atmosphere, such as nitrogen or argon, and with proper safety precautions to prevent exposure to air and moisture.

92601-82-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92601-82-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,0 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 92601-82:
(7*9)+(6*2)+(5*6)+(4*0)+(3*1)+(2*8)+(1*2)=126
126 % 10 = 6
So 92601-82-6 is a valid CAS Registry Number.

AN INEXPENSIVE INFLUENCE MODIFICATION OF THE SIMMONS-SMITH REACTION: THE FORMATION OF BROMOMETHYLZINC BROMIDE AS STUDIED BY NMR SPECTROSCOPY

Fabisch, Bodo,Mitchell, Terence N.

, p. 219 - 222 (2007/10/02)

Bromomethylzinc bromide, prepared from zinc metal and methylene bromide in tetrahydrofuran, gives moderate to good yields of cyclopropanation product when treated with olefins, thus providing an inexpensive alternative to the Simmons-Smith procedure.An NMR study of the reaction between metallic zinc and methylene bromide has been carried out: in addition to bromomethylzinc bromide and dimethylzinc, two further species were observed and tentatively identified as bis(bromomethyl)zinc a di- or tri-zinc compound.
