Uses
2-Thienylzinc bromide can be used as:A starting material in the synthesis of heteroaryl sulfonamides by reacting with 2,4,6-trichlorophenyl chlorosulfate.A substrate in the synthesis of naphthacenodithiophene derived polymers, which are used in transistor and solar cell devices.An intermediate in the preparation of isoquinoline derived AICARFT inhibitors.
Check Digit Verification of cas no
The CAS Registry Mumber 45438-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,5,4,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 45438-80:
(7*4)+(6*5)+(5*4)+(4*3)+(3*8)+(2*8)+(1*0)=130
130 % 10 = 0
So 45438-80-0 is a valid CAS Registry Number.

New chemical synthesis of functionalized arylzinc compounds from aromatic or thienyl bromides under mild conditions using a simple cobalt catalyst and zinc dust
Fillon, Hyacinthe,Gosmini, Corinne,Perichon, Jacques
, p. 3867 - 3870 (2007/10/03)
A new chemical method for the preparation of arylzinc intermediates is described in acetonitrile, on the basis of the activation of aryl bromides by low-valent cobalt species arising from the reduction of cobalt halide by zinc dust. This procedure allows for the synthesis of a variety of functionalized aryl- and thienylzinc species in good to excellent yields. The versatility and the simplicity of that original method represent an alternative to most known procedures.
