39220-69-4 Usage
General Description
1-bromo-4-(1-methylpropyl)benzene, also known as p-tert-butylbromobenzene, is a chemical compound with the molecular formula C10H13Br. It is an organic compound that belongs to the class of benzene and substituted derivatives, and it contains a bromine atom attached to the fourth carbon atom of a benzene ring, with a 1-methylpropyl group (tert-butyl group) attached to the benzene ring. 1-bromo-4-(1-methylpropyl)benzene is commonly used in organic synthesis and as a reagent in chemical reactions. It is a colorless to pale yellow liquid with a strong, aromatic odor and is insoluble in water but soluble in organic solvents such as ethanol and acetone. It is important to handle this compound with care as it is a flammable liquid and may cause skin and eye irritation upon contact.
Check Digit Verification of cas no
The CAS Registry Mumber 39220-69-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,2 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39220-69:
(7*3)+(6*9)+(5*2)+(4*2)+(3*0)+(2*6)+(1*9)=114
114 % 10 = 4
So 39220-69-4 is a valid CAS Registry Number.

Bioinspired Metal-Free Formal Decarbonylation of α-Branched Aliphatic Aldehydes at Ambient Temperature
Richter, Sven C.,Oestreich, Martin
supporting information, p. 8508 - 8512 (2019/06/04)
A sequence of a Baeyer–Villiger oxidation and a Lewis acid-promoted reduction of the resulting formate with Et3SiH enabled the metal-free formal decarbonylation of tertiary and secondary aliphatic aldehydes. The new methodology mimics the biosynthetic decarbonylation pathway through oxidative C?C bond cleavage rather than the C(O)?H bond activation known from conventional Tsuji–Wilkinson-type reactions. The substrate scope is complementary to existing transition-metal-catalyzed protocols.
