400-13-5 Usage

General Description

2-Fluorothiophene is a chemical compound with the molecular formula C4H3FS. It is a colorless to light yellow liquid with a distinctive unpleasant odor. 2-Fluorothiophene is often used as a building block in the synthesis of pharmaceuticals and agrochemicals. It is also utilized in the production of dyes, polymers, and organic materials. The compound is known for its potential applications in materials science, such as in the creation of conducting polymers and organic electronics. Due to its flammability and potential health hazards, proper handling and safety precautions are necessary when working with 2-Fluorothiophene.

Check Digit Verification of cas no

The CAS Registry Mumber 400-13-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 400-13:
(5*4)+(4*0)+(3*0)+(2*1)+(1*3)=25
25 % 10 = 5
So 400-13-5 is a valid CAS Registry Number.

Cascade iodination-fluorination synthesis of 2-fluorothiophene and 5-fluoro-2-thienyliodonium salts

Onys'ko, Petro P.,Kim, Tetyana V.,Kiseleva, Olena I.,Rassukana, Yuliya V.,Gakh, Andrei A.

body text, p. 501 - 504 (2010/01/14)

The first synthesis of fluorine-containing 2-thienyliodonium salts was accomplished using cascade iodination-fluorination. According to this methodology, thiophene is first converted to bis(2-thienyl)iodonium hexafluorophosphate using an electrophilic iodination reaction. Upon heating with potassium fluoride, this salt undergoes regioselective fluorination producing 2-fluorothiophene. 2-Fluorothiophene is then iodinated again to yield fluorothienyliodonium salts.

THE FLUORINATION OF SIMPLE FIVE-MEMBERED HETEROAROMATIC COMPOUNDS WITH ELEMENTAL FLUORINE

Cerichelli, Giorgio,Crestoni, Maria Elisa,Fornarini, Simonetta

, p. 749 - 755 (2007/10/02)

The reaction of elemental fluorine with five-membered heteroaromatics under controlled conditions proceeds cleanly, yielding major substitution products in the case of thiophene (1) and N-methylpyrrole (2) or 1,4-addition products in the case of furan (3), while pyrrole (4) gives only tars.The site of fluorine substitution on N-methylpyrrole remarkably favours the β carbon atoms by a factor of ca. 3 over the α carbons.The α/β substitution ratio for 1 (1.9) and 2 (0.28) and the intermolecular reactivity order N-methylpyrrole > thiophene > benzene agrees with a polar electrophilic substitution mechanism.Also the predominantly syn 1,4-addition to furan conforms to the polar syn addition of F2 to double bonds.
