42565-25-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42565-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,6 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42565-25:
(7*4)+(6*2)+(5*5)+(4*6)+(3*5)+(2*2)+(1*5)=113
113 % 10 = 3
So 42565-25-3 is a valid CAS Registry Number.

InCl3-Zn. A novel reduction system for the deoxygenative coupling of carbonyl compounds to olefins

Barman,Thakur,Prajapati,Sandhu

, p. 515 - 516 (2001)

A simple and inexpensive procedure for the deoxygenative homo-coupling and cross-coupling of carbonyl compounds with InCl3-Zn system in dry acetonitrile at ambient pressure is achieved. The procedure gives excellent yields of E-olefinic products.

Stereochemistry and Side Products in Reductive Coupling of Alkyl Aryl Ketones to 1,2-Dialkyl-1,2-diarylethylenes

Leimner, Juergen,Weyerstahl, Peter

, p. 3697 - 3705 (2007/10/02)

The reductive coupling of alkyl aryl ketones 1 - 3 and 7 - 9 by low valent titanium salts yields predominantly the (Z)-isomers of 11 - 13 and 17 - 19.Evidence is given by 1H NMR spectroscopy.This behavior can be explained by ?-complex formation of phenyl rings with Ti0.Severe steric hindrance, however, favors the (E)-isomers ( -> 14 and 15).Donor groups in p-position, particularly, give increasing amounts of pinacols, 23 - 27, which undergo rearrangement to the ketones 28 and 29.
