2-(2,6-dichlorobenzyloxy)pyridine is an organic compound characterized by its molecular formula C12H8Cl2NO. It features a pyridine ring, which is a six-membered aromatic ring containing one nitrogen atom, and a 2,6-dichlorobenzyl group attached to the pyridine at the 2-position. The 2,6-dichlorobenzyl group consists of a benzene ring with two chlorine atoms at the 2nd and 6th positions, and a methyl group attached to the benzene at the 1st position, which is connected to the pyridine ring through an oxygen atom. 2-(2,6-dichlorobenzyloxy)pyridine is often used in the synthesis of various pharmaceuticals and agrochemicals due to its unique structure and reactivity. It is important to handle 2-(2,6-dichlorobenzyloxy)pyridine with care, as it may have potential health and environmental impacts due to its chlorine content and aromatic structure.

Check Digit Verification of cas no

The CAS Registry Mumber 66496-55-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,9 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66496-55:
(7*6)+(6*6)+(5*4)+(4*9)+(3*6)+(2*5)+(1*5)=167
167 % 10 = 7
So 66496-55-7 is a valid CAS Registry Number.

Preparation of N-alkyl 2-pyridones via a lithium iodide promoted oto N-alkyl migration: Scope and mechanism

Tasker, Sarah Z.,Bosscher, Michael A.,Shandro, Christina A.,Ryu, Keun Ah,Snapper, Gregory S.,Utter, Jarrad M.,Anderson, Carolyn E.,Lanni, Erica L.,Ellsworth, Bruce A.

, p. 8220 - 8230,11 (2020/10/15)

An efficient and inexpensive LiI-promoted O- to N-alkyl migration of 2-benzyloxy-, 2-allyloxy-, and 2-propargyloxypyridines and heterocycles is reported. The reaction produces the corresponding N-alkyl 2-pyridones and analogues under green, solvent-free conditions in good to excellent yields (30 examples, 20-97% yield). This method has been shown to be intermolecular and requires heat and lithium cation to occur.

Synthesis of substituted N-benzyl pyridones via an O- To N-alkyl migration

Lanni, Erica L.,Bosscher, Michael A.,Ooms, Bartel D.,Shandro, Christina A.,Ellsworth, Bruce A.,Anderson, Carolyn E.

, p. 6425 - 6428 (2008/12/21)

(Chemical Equation Presented) A new LiI-promoted O- to N-alkyl migration has been developed for the conversion of O-alkylated 2-hydroxy pyridines, quinolines, and pyrimidines to the corresponding N-alkylated heterocycles in good to excellent yields (57-99%). This method serves as an efficient means for the preparation of N-benzyl pyridones, quinolones, and pyrimidones.
