2,5-Bis(butylamino)-3,6-dichlorocyclohexa-3,5-diene-1,4-dione is a disubstituted product formed through the autocatalytic reaction of chloranil with excess n-butylamine, involving an initial charge-transfer complex intermediate. The reaction proceeds with distinct kinetic and thermodynamic parameters, ultimately yielding the bis(butylamino) derivative as the final product.

Check Digit Verification of cas no

The CAS Registry Mumber 28987-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,9,8 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28987-70:
(7*2)+(6*8)+(5*9)+(4*8)+(3*7)+(2*7)+(1*0)=174
174 % 10 = 4
So 28987-70-4 is a valid CAS Registry Number.

Kinetics and Mechanism of the Reactions between Chloranil and n-Butylamine in Cyclohexane Solution

Monzo, Isidro S.,Palou, Juan,Roca, Jose,Valero, Rosa

, p. 1995 - 1998 (1988)

Interaction between chloranil (CA) and n-butylamine (A) at several temperatures has been studied by u.v.-visible spectroscopy.Kinetic and thermodynamic parameters, as well as a mechanism, have been proposed for this reaction.The results indicate the initial formation of charge-transfer complexes between CA and A, in the presence of an excess of amine, which decomposes to give a final product (D) (disubstituted product of CA).The reaction path is autocatalysed by the presence of amine.

NEW SYNTHESIS OF TRIPHENODITHIAZINES AND TRIPHENODITHIAZINEQUINOES.

Nishi,Hatada,Kitahara

, p. 1482 - 1486 (2007/10/02)

A new class of 6,13-bis(arylamino)triphenodithiazines has been synthesized by condensing chloranil with arylamines followed by the reaction of the resulting 2,5-bis(arylamino)-3,6-dichloro-1,4-benzoquinones with zinc 2-aminobenzenthiolates in the presence
