General Description
1-Iodo-3,5-dimethylbenzene (5-Iodo-m-xylene) is an aryl halide. It can be obtained from 5-bromo-m-xylene, via copper-catalyzed halogen exchange reaction, in the presence of NaI or KI in n-BuOH or DMF (solvents). It undergoes reaction with phenol in the presence of CuFe2O4 nano powder as a recyclable catalyst to afford 1,3-dimethyl-5-phenoxybenzene.
Check Digit Verification of cas no
The CAS Registry Mumber 22445-41-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,4 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22445-41:
(7*2)+(6*2)+(5*4)+(4*4)+(3*5)+(2*4)+(1*1)=86
86 % 10 = 6
So 22445-41-6 is a valid CAS Registry Number.

Sulfur contamination due to quenching of halogenation reactions with sodium thiosulfate: Resolution of process problems via improved quench protocols
Xiang, Yanqiao,Caron, Pierre-Yves,Lillie, Brett M.,Vaidyanathan, Rajappa
, p. 116 - 119 (2008)
Many metal-mediated cross-couplings involve the use of organic halides, which are usually accessed by halogenation reactions. Cross-couplings are sensitive to the presence of impurities in the halides. This paper describes the origin of one such problematic impurity (sulfur) during the synthesis of organic halides and proposes alternatives to minimize or eliminate its formation.

A convenient, efficient and practical visible-light-induced decarboxylative iodination of aromatic carboxylic acids has been developed, and the corresponding aryl iodides were obtained in good yields. The method shows some advantages including the use of readily available aromatic carboxylic acids as the starting materials, simple and mild conditions, high efficiency, wide substrate scope and tolerance of various functional groups.
Easy Access to Difluoromethylene-Containing Arene Analogues through Palladium-Catalysed C–H Olefination

An efficient palladium-catalysed ortho-C–H olefination of α,α-difluorophenylacetic acid derivatives using 8-aminoquinoline as a bidentate directing group has been developed. A range of olefinated arenes can thus be synthesized in a concise way. This reaction provides an easy and straightforward route to a panel of difluoromethylated arene analogues in moderate to good yields, with a satisfactory tolerance of common functional groups. Transformation of the products into a variety of other difluoromethylene-containing compounds demonstrates the utility of this method.
