935-77-3 Usage

General Description

1H-Inden-1-one, 2,3-dihydro-3-methyl-, (3S)-, also known as 3S-2,3-dihydro-3-methyl-1H-inden-1-one, is a chemical compound with the molecular formula C10H10O. It is a chiral molecule, meaning it has a specific spatial arrangement of atoms, and the (3S)- designation refers to its stereochemistry. 1H-Inden-1-one, 2,3-dihydro-3-methyl-, (3S)- is commonly used in the production of fragrances and perfumes due to its pleasant odor. It may also have potential applications in pharmaceuticals and organic synthesis. Additionally, it is a colorless to pale yellow liquid at room temperature and is relatively stable under normal conditions.

Check Digit Verification of cas no

The CAS Registry Mumber 935-77-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 935-77:
(5*9)+(4*3)+(3*5)+(2*7)+(1*7)=93
93 % 10 = 3
So 935-77-3 is a valid CAS Registry Number.

Mild, efficient friedel-Crafts acylations from carboxylic acids using cyanuric chloride and AlCl3

Kangani, Cyrous O.,Day, Billy W.

, p. 2645 - 2648 (2008)

(Chemical Equation Presented) A mild method for Friedel-Crafts acylation with aromatic and aliphatic carboxylic acids using cyanuric chloride, pyridine, and AlCl3 was developed. Both inter- and intramolecular acylations were achieved at room temperature in high yield and in very short reaction times.

Cobalt-catalyzed enantioselective intramolecular hydroacylation of ketones and olefins

Yang, Junfeng,Yoshikai, Naohiko

supporting information, p. 16748 - 16751 (2015/02/05)

Cobalt-chiral diphoshine catalytic systems promote intramolecular hydroacylation reactions of 2-acylbenzaldehydes and 2-alkenylbenzaldehydes to afford phthalide and indanone derivatives, respectively, in moderate to good yields with high enantioselectivities. The ketone hydroacylation did not exhibit a significant H/D kinetic isotope effect (KIE) with respect to the aldehyde C-H bond, indicating that C-H activation would not be involved in the rate-limiting step.
