Tropone azine, also known as 2,4,6-cycloheptatrien-1-one azine, is a nitrogen-containing organic compound derived from tropone, a cyclic trimer of acetylene. It features a seven-membered ring structure with alternating double bonds and a nitrogen atom incorporated into the ring, forming a diazine. Tropone azine is an important intermediate in the synthesis of various natural products and pharmaceuticals, such as tropane alkaloids, due to its unique electronic properties and reactivity. Its chemical properties include the ability to undergo cycloaddition reactions, making it a valuable building block in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 86428-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,4,2 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86428-01:
(7*8)+(6*6)+(5*4)+(4*2)+(3*8)+(2*0)+(1*1)=145
145 % 10 = 5
So 86428-01-5 is a valid CAS Registry Number.

FORMATIONS OF 1,1'-BIAZAAZULANONES THROUGH, -TYPE CYCLOADDITION REACTIONS OF TROPONE AZINE WITH HETEROCUMULENES

Ito, Kazuaki,Saito, Katsuhiro,Takahashi, Kensuke

, p. 2339 - 2348 (2007/10/02)

Reaction of N-aryl-2,4,6-cycloheptatrien-1-imine with hydrazine afforded tropone azine, which reacted with chloroketenes to give 1,1'-biazaazulanones via -type cycloadducts followed by elimination of hydrochloride.The similar reaction using phenyl isocyanate afforded a -type 1:2 cycloadduct, while the reaction with phenyl isocyanate yielded only a 1:1 cycloadduct. 15N and 13C nmr spectra on C=N bond of tropone azine showed a minor contribution of a dipolar structure compared with the case of N-aryl-2,4,6-cycloheptatrien-1-imines.
