17171-73-2 Usage

General Description

1,2-Dibutylbenzene is a chemical compound with the molecular formula C18H22. It is a colorless liquid that is insoluble in water and is commonly used as a solvent in various industrial and commercial applications. 1,2-Dibutylbenzene is a member of the aromatic hydrocarbons family and is derived from benzene. It is primarily used as a solvent in the manufacturing of rubber, plastics, and resins. Additionally, it is also used in the production of adhesives, coatings, and other chemical products. However, it is important to handle 1,2-Dibutylbenzene with care as it has been classified as a category 3 carcinogen and may have harmful effects on human health and the environment.

Check Digit Verification of cas no

The CAS Registry Mumber 17171-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,7 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 17171-73:
(7*1)+(6*7)+(5*1)+(4*7)+(3*1)+(2*7)+(1*3)=102
102 % 10 = 2
So 17171-73-2 is a valid CAS Registry Number.

Two flavors of PEPPSI-IPr: Activation and diffusion control in a single NHC-ligated Pd catalyst?

Larrosa, Igor,Somoza, Clara,Banquy, Alexandre,Goldup, Stephen M.

supporting information; experimental part, p. 146 - 149 (2011/03/20)

Abnormal reactivity has been observed in Negishi, Suzuki-Miyaura, and Kumada-Tamao-Corriu cross-couplings in which PEPPSI-IPr (where PEPPSI stands for pyridine enhanced precatalyst preparation, stabilization, and initiation and IPr refers to the NHC ligand) is employed, implicating the presence of two distinct Pd0 species in the catalytic cycle. Polybrominated arenes and organometallic reagents react selectively to give the product of exhaustive polysubstitution regardless of the initial reaction stoichiometry. Competition experiments suggest that, after an initial activation controlled oxidative addition, reductive elimination produces an ultrareactive Pd0 species which consumes all remaining C-Br bonds in the molecule under diffusion control.

Synthesis of Diacetylene Macrocycles Derived from 1,2-Diethynylbenzene Derivatives: Structure and Reactivity of the Strained Cyclic Dimer

Zhou, Qin,Carroll, Patrick J.,Swager, Timothy M.

, p. 1294 - 1301 (2007/10/02)

Diacetylene macrocycles 2-4 (n=1-3) (R=H, C4H9, C6H13, C10H21, C12H25, OC10H21) have been prepared from the oxidative coupling of 1,2-diethynylbenzene derivatives.These compounds can be produced in useful quantities and are of interest as precursors to novel conjugated organic polymers.The reported results indicate that when the R groups are large the dimeric macrocycle (n=1) can be prepared in as high as 74percent yield from the corresponding 1,2-diethynylbenzene in a one-step procedure.An alternate multistep procedure was found to produce the tetrameric macrocycle (n=3,R=C6H13) in 45percent yield.The highly strained dimeric macrocycle was characterized by an X-ray structure and was found to be very reactive.The dimers undergo a rapid very exothermic polymerization at 100-125 deg C, indicative of a chain reaction.Reaction of the dimeric macrocycles with iodine results in intramolecular cyclization and a new 20? electron tetraiodide fused ring system.Reaction of the tetraiodide with oxygen produces a related compound in which two of the iodides have been converted to ketones.

SELECTIVE MONO-ALKYLATION AND ARYLATION OF AROMATIC DIHALIDES BY PALLADIUM-CATALYZED CROSS-COUPLING WITH THE GRIGNARD AND ORGANOZINC REAGENTS

Minato, Akio,Tamao, Kohei,Hayashi, Tamio,Suzuki, Keizo,Kumada, Makoto

, p. 845 - 848 (2007/10/02)

Dibromobenzene, dibromothiophenes, dichloro- and dibromopyridine are highly selectively mono-alkylated and arylated with Grignard or organozinc reagents in the presence of palladium complexes as catalysts.
