General Description
4-Bromophenylzinc iodide is a chemical compound with the formula C6H5BrZnI. It is a zinc organometallic reagent commonly used in organic synthesis as a source of the 4-bromophenyl group. 4-BROMOPHENYLZINC IODIDE is a valuable tool in cross-coupling reactions such as the Negishi coupling, which forms carbon-carbon bonds between an organic halide and an organozinc reagent. 4-Bromophenylzinc iodide is a versatile and important reagent in the field of organic chemistry, enabling the construction of complex organic molecules through C-C bond formation.
Check Digit Verification of cas no
The CAS Registry Mumber 148651-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,6,5 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 148651-39:
(8*1)+(7*4)+(6*8)+(5*6)+(4*5)+(3*1)+(2*3)+(1*9)=152
152 % 10 = 2
So 148651-39-2 is a valid CAS Registry Number.

Stabilised arylzinc iodide, prepared by direct insertion of zinc into aryl iodides, were used as nucleophiles in the Hayashi Rh-catalysed enantioselective conjugate addition to enones. The reaction conditions were optimized in the addition of phenylzinc i
Ultrasound-Promoted Synthesis of Arylzinc Compounds Using Zinc Powder and Their Application to Palladium(0)-Catalyzed Synthesis of Multifunctional Biaryls
Takagi, Kentaro
, p. 469 - 472 (2007/10/02)
Arylzinc compounds containing electron-withdrawing groups such as CO2CH3, CON(CH3)2, CN, Br, Cl, or CF3 at ortho position were prepared readily by the ultrasound-promoted reaction of aryl iodides with zinc powder, which were applied to palladium(0)-catalyzed cross-coupling with aryl halides to afford unsymmetrical and multifunctional biaryls in good yields.
