19069-63-7 Usage

General Description

4-CHLORO-3-PHENYLPYRIDINE is a chemical compound with the molecular formula C11H8ClN. It is a pyridine derivative with a chlorine atom at the 4th position and a phenyl group at the 3rd position of the pyridine ring. 4-CHLORO-3-PHENYLPYRIDINE is commonly used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and other organic compounds. It is also used as a building block in the production of various heterocyclic compounds. 4-CHLORO-3-PHENYLPYRIDINE is considered to be potentially hazardous, and proper safety precautions should be taken when handling and storing this chemical.

Check Digit Verification of cas no

The CAS Registry Mumber 19069-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,6 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19069-63:
(7*1)+(6*9)+(5*0)+(4*6)+(3*9)+(2*6)+(1*3)=127
127 % 10 = 7
So 19069-63-7 is a valid CAS Registry Number.

Selective Halogenation of Pyridines Using Designed Phosphine Reagents

Alegre-Requena, Juan V.,Levy, Jeffrey N.,Liu, Renrong,McNally, Andrew,Paton, Robert S.

supporting information, p. 11295 - 11305 (2020/07/13)

Halopyridines are key building blocks for synthesizing pharmaceuticals, agrochemicals, and ligands for metal complexes, but strategies to selectively halogenate pyridine C-H precursors are lacking. We designed a set of heterocyclic phosphines that are installed at the 4-position of pyridines as phosphonium salts and then displaced with halide nucleophiles. A broad range of unactivated pyridines can be halogenated, and the method is viable for late-stage halogenation of complex pharmaceuticals. Computational studies indicate that C-halogen bond formation occurs via an SNAr pathway, and phosphine elimination is the rate-determining step. Steric interactions during C-P bond cleavage account for differences in reactivity between 2- and 3-substituted pyridines.

Site-Selectivity in the Reaction of 3-Substituted Pyridine 1-Oxides with Phosphoryl Chloride

Yamanaka, Hiroshi,Araki, Tomio,Sakamoto, Takao

, p. 2244 - 2247 (2007/10/02)

Site-selectivity in the reaction of 3-substituted pyridine 1-oxide with phosphoryl chloride was investigated.When a strongly electron-withdrawing group (e.g.CN, CONRR', COOR, or NO2) was substituted at the 3-position, the reaction of 3-substituted pyridine 1-oxides with phosphoryl chloride yielded 3-substituted 2-chloropyridines as the main products.Keywords- site-selectivity; 3-substituted pyridine 1-oxide; phosphoryl chloride; 3-substituted 2-chloropyridine; chlorination
