[1,2,3]triazolo[1,5-f]phenanthridine is a heterocyclic compound characterized by a triazole ring fused to a phenanthridine core. This complex structure is composed of a phenanthridine, which is a tricyclic aromatic system with a central pyridine ring, and a triazole, a five-membered ring containing three nitrogen atoms. The specific fusion of these two rings at positions 1, 2, and 3 of the triazole and at position 1, 5 of the phenanthridine gives [1,2,3]triazolo[1,5-f]phenanthridine its unique chemical properties. It is an important scaffold in medicinal chemistry due to its potential applications in the development of new drugs, particularly in the area of anticancer agents, as it can form stable complexes with metal ions and exhibit significant biological activity. The synthesis and study of such compounds are of interest to researchers in the field of organic and medicinal chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 34456-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,4,5 and 6 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34456-70:
(7*3)+(6*4)+(5*4)+(4*5)+(3*6)+(2*7)+(1*0)=117
117 % 10 = 7
So 34456-70-7 is a valid CAS Registry Number.

Different behavior of nitrenes and carbenes on photolysis and thermolysis: Formation of azirine, ylidic cumulene, and cyclic ketenimine and the rearrangement of 6-phenanthridylcarbene to 9-phenanthrylnitrene

Kvaskoff, David,Bednarek, Pawel,George, Lisa,Pankajakshan, Sreekumar,Wentrup, Curt

, p. 7947 - 7955 (2005)

Flash vacuum thermolysis (FVT) of 9-azidophenanthrene 8, 6-(5-tetrazolyl)phenanthridine 18, and [1,2,3]triazolo[l,5-f]phenanthridine 19 yields 9-cyanofluorene 12 as the principal product and 4-cyanofluorene as a minor product. In all cases, when the product is condensed at or below 77 K, the seven-membered ring ketenimine 24 is detectable by IR spectroscopy (1932 cm-1) up to 200 K. Photolysis of Ar matrix isolated 8 at λ = 308 or 313 nm generates at first the azirine 26, rapidly followed by the ylidic cumulene 27. The latter reverts to azirine 26 at λ > 405 nm, and the azirine reverts to the ylidic cumulene at 313 nm. Nitrene 9 is observed by ESR spectroscopy following FVT of either azide 8, tetrazole 18, or triazole 19 with Ar matrix isolation of the products. Nitrene 9 and carbene 21 are observed by ESR spectroscopy in the Ar matrix photolyses of azide 8 and triazole 19, respectively.
