2-Chlorobenzyl 4-fluorophenyl sulfide is an organic compound with the chemical formula C13H10ClFOS. It is a colorless to pale yellow liquid with a molecular weight of 262.73 g/mol. 2-chlorobenzyl 4-fluorophenyl sulfide is characterized by the presence of a sulfur atom that connects a 2-chlorobenzyl group (a benzyl group with a chlorine atom at the 2nd position) to a 4-fluorophenyl group (a phenyl group with a fluorine atom at the 4th position). It is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique structural features. The compound is sensitive to heat and light, and it is typically stored under cool, dry conditions to maintain its stability. Its applications span across various industries, making it a valuable chemical in the realm of organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 328-30-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,2 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 328-30:
(5*3)+(4*2)+(3*8)+(2*3)+(1*0)=53
53 % 10 = 3
So 328-30-3 is a valid CAS Registry Number.

Preparation of polyfunctional arylmagnesium, arylzinc, and benzylic zinc reagents by using magnesium in the presence of LiCl

Piller, Fabian M.,Metzger, Albrecht,Schade, Matthias A.,Haag, Benjamin A.,Gavryushin, Andrei,Knochel, Paul

experimental part, p. 7192 - 7202 (2010/03/05)

The presence of LiCl considerably facilitates the insertion of magnesium into various aromatic and heterocyclic bromides. Several functional groups, such as -OBoc, -OTs, -Cl, -F, -CF3, -OMe, -NMe2, and -N 2NR2, are well tolerated. The presence of a cyano group leads in some cases to competitive reduction of the organic halide to the corresponding ArH compound. The presence of sensitive groups such as methyl or ethyl ester is tolerated upon in situ trapping of the intermediate magnesium reagent with ZnCl2. This method can also be applied to the preparation of functionalized benzylic zinc reagents from benzylic chlorides. In the case of di- or tribromoaryl derivatives, directing groups such as -OPiv, -OTs, -N2NR2, or -OAc orient the zinc insertion (Zn/LiCl) to the ortho-position, while the reaction with Mg/LiCl or Mg/LiCl/ZnCl 2 leads to regioselective insertion into the para-carbon-bromine bond. Large-scale experiments (20-100 mmol) for all of the metalation procedures are described.
