10-(4-nitroanilino)-5H-dibenzo[a,d]cyclohepten-5-one is a complex organic compound with the molecular formula C17H12N2O3. It is a derivative of dibenzo[a,d]cyclohepten-5-one, featuring a nitroaniline group attached to the 10th position. 10-(4-nitroanilino)-5H-dibenzocyclohepten-5-one is characterized by its aromatic structure, with two benzene rings fused to a cycloheptene ring. The nitro group (-NO2) on the aniline moiety introduces a strong electron-withdrawing effect, which can significantly influence the compound's reactivity and physical properties. It is likely to be used in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and potential for further functionalization.

73078-91-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73078-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,7 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73078-91:
(7*7)+(6*3)+(5*0)+(4*7)+(3*8)+(2*9)+(1*1)=138
138 % 10 = 8
So 73078-91-8 is a valid CAS Registry Number.

Syntheses and Reactions of Spiroanthronetriazolines

Hirakawa, Kiyoichi,Ito, Tsutomu,Okubo, Yoshiji,Nakazawa, Sho

, p. 1668 - 1672 (2007/10/02)

Quinone methide 1a reacts with aryl azides 2 to give the corresponding spiroanthronetriazolines 3 along with byproducts, collected in Table I, which are formed by the thermal reaction of 3 or 1a.Quinone methide 1b adds to azides 2 to give spiroanthronetriazolines 5 or their subsequent products.Pyrolysis of 3 regenerates the starting quinone methide 1a and azide 2, and their photolysis leads to 1a.Pyrolysis and photolysis of 5 yield aryliminoanthrone 7, arylaminodibenzocycloheptenone 12, or its isomer 19.Attempts to convert 3 and 5 into spiroanthroneaziridines 14 and 15, respectively, were unsuccessful.Reactions of 3 and 5 with acid catalysts give the rearrangement products dibenzocycloheptenediones 23 and 24, respectively, in high yields.These reactions are discussed in mechanistic terms.
