3-Hexanone, 1-phenyl-1-(phenylamino)-, also known as N-Phenyl-1-phenylmethyl-3-hexanone, is an organic compound with the chemical formula C17H19NO. It is a colorless to pale yellow liquid with a molecular weight of 251.34 g/mol. 3-Hexanone, 1-phenyl-1-(phenylamino)- is characterized by the presence of a hexanone group (a six-carbon ketone chain), a phenyl group (a benzene ring), and a phenylamino group (an amino group attached to a phenyl group). It is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Due to its chemical structure, it may exhibit properties such as low solubility in water and high solubility in organic solvents. It is important to handle 3-Hexanone, 1-phenyl-1-(phenylamino)- with care, as it may have potential health and environmental hazards, and appropriate safety measures should be taken during its use and storage.

735-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 735-68-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 5 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 735-68:
(5*7)+(4*3)+(3*5)+(2*6)+(1*8)=82
82 % 10 = 2
So 735-68-2 is a valid CAS Registry Number.

Hf(OTf)4 as a highly potent catalyst for the synthesis of Mannich bases under solvent-free conditions

Gong, Shan-Shan,Han, Shuai-Bo,Liu, Rong,Peng, Xiao-Chong,Sun, Qi,Wei, Jing-Ying

, (2020/01/28)

Hf(OTf)4 was identified as a highly potent catalyst (0.1–0.5 mol%) for three-component Mannich reaction under solvent-free conditions. Hf(OTf)4-catalyzed Mannich reaction exhibited excellent regioselectivity and diastereoselectivity when alkyl ketones were employed as substrates. 1H NMR tracing of the H/D exchange reaction of ketones in MeOH-d4 indicated that Hf(OTf)4 could significantly promote the keto-enol tautomerization, thereby contributing to the acceleration of reaction rate.
