13654-48-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13654-48-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,5 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13654-48:
(7*1)+(6*3)+(5*6)+(4*5)+(3*4)+(2*4)+(1*8)=103
103 % 10 = 3
So 13654-48-3 is a valid CAS Registry Number.

Visible light induced photocatalytic conversion of enamines into amides

Li, Jing,Cai, Shunyou,Chen, Jietao,Zhao, Yaohong,Wang, David Zhigang

supporting information, p. 1626 - 1628 (2014/07/08)

A series of enamines were photocatalytically cleaved to produce amide products under simple visible-light irradiation from a 45 W household light bulb. Mechanistically, the reactions appear to involve photosensitized formation of a singlet oxygen intermediate and a subsequent [2+2] cycloaddition event. Georg Thieme Verlag Stuttgart, New York.

The Chemistry of Aryllead(IV) Tricarboxylates. Reaction with Enamines

May, George L.,Pinhey, John T.

, p. 1859 - 1871 (2007/10/02)

The treatment of 1-morhpholinocyclopentene (1a) with p-methoxyphenyllead triacetate (2a) in chloroform provides a simple high-yielding route to 2-(4-methoxyphenyl)cyclopentanone (3a).This arylation reaction of enamines has been investigated with a variety of substrates and a number of aryllead triacetates.The reaction has been found to be very sensitive to steric effects and is thus a useful synthetic method in a relatively small number of cases.Acetoxylation is a major competing reaction with those enamines of cyclic ketones which give a low to moderate yield of arylated product.
