General Description

3,4-Dichlorobenzyl iodide is a chemical compound with the molecular formula C7H5Cl2I. It is a white to light yellow solid that is commonly used as a reagent in organic synthesis. 3,4-DICHLOROBENZYL IODIDE is known for its ability to serve as an alkylating agent, being used to introduce the 3,4-dichlorobenzyl group into various molecules. It is a versatile reagent in the field of pharmaceutical and agrochemical research, and is often utilized in the synthesis of biologically active compounds. Additionally, 3,4-dichlorobenzyl iodide is also used in the manufacturing of dyes and other fine chemicals. However, it should be handled with caution as it is a toxic and potentially hazardous compound.

Check Digit Verification of cas no

The CAS Registry Mumber 142523-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,5,2 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142523-67:
(8*1)+(7*4)+(6*2)+(5*5)+(4*2)+(3*3)+(2*6)+(1*7)=109
109 % 10 = 9
So 142523-67-9 is a valid CAS Registry Number.

Conversion of Aryl Aldehydes to Benzyl Iodides and Diarylmethanes by H3PO3/I2

Lv, Fang,Xiao, Jing,Xiang, Junchun,Guo, Fengzhe,Tang, Zi-Long,Han, Li-Biao

, p. 3081 - 3088 (2021/02/01)

For the first time, H3PO3 was used as both the reducing reagent and the promotor in the reductive benzylation reactions with aryl aldehydes. By using a H3PO3/I2 combination, various aromatic aldehydes underwent iodination reactions and Friedel-Crafts type reactions with arenes via benzyl iodide intermediates, readily producing benzyl iodides and diarylmethanes in good yields. Intramolecular cyclization reactions also took place, giving the corresponding cyclic compounds. This new strategy features easy-handling, low-cost, and metal-free conditions.

Preparation method of benzyl iodide and derivatives thereof

-

Paragraph 0107-0111, (2020/06/09)

The invention discloses a preparation method of benzyl iodide and derivatives thereof. The preparation method comprises the following steps: under the reduction action of sodium borohydride, a benzylalcohol compound shown as a formula I reacts with elemental iodine to obtain benzyl iodide shown as a formula II and derivatives thereof; in the formula I and the formula II, R represents one or moresubstituents on a benzene ring and is selected from at least one of aryl, substituted or unsubstituted alkyl, halogen and nitro. The preparation method of benzyl iodide and derivatives thereof is scientific and reasonable, sodium borohydride which is mild in reactivity, low in price and easily available is used as a reducing agent, and elemental iodine is convenient and easily available; in addition, the preparation method has the characteristics of simplicity and convenience in operation, high synthesis yield, easiness in product purification, environmental friendliness and the like.
