Bicyclo[4.1.0]hepta-2,4-diene-7,7-dicarbonitrile, also known as norbornadiene dicarbonitrile or norbornadiene-7,7-dicarbonitrile, is a bicyclic organic compound with the molecular formula C9H8N2. It features a norbornadiene core, which is a seven-membered ring with two carbon atoms connected to a six-membered ring. The molecule has two nitrile groups (-CN) attached to the carbon atoms at positions 7 and 7. Bicyclo[4.1.0]hepta-2,4-diene-7,7-dicarbonitrile is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique structure and reactivity. It is typically synthesized through the Diels-Alder reaction of cyclopentadiene with maleonitrile and can be further functionalized to access a wide range of derivatives.

1618-16-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1618-16-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,1 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1618-16:
(6*1)+(5*6)+(4*1)+(3*8)+(2*1)+(1*6)=72
72 % 10 = 2
So 1618-16-2 is a valid CAS Registry Number.

THERMOLYSIS AND PHOTOLYSIS OF 4-DIAZO-1,2,3-TRIAZOLES IN BENZENOID SOLVENTS, SYSTEMS WHICH REVEAL DECOMPOSITION OF DIAZO COMPOUNDS TO CARBENES TO DIAZO COMPOUNDS TO CARBENES.

Hui, H. K.-W.,Shechter, H.

, p. 5115 - 5118 (2007/10/02)

4-Diazo-1,2,3-triazoles thermolyze and photolyze to 4H-1,2,3-triazolylidenes which (1) convert benzenes to 4-phenyl-1,2,3-triazoles or/and (2) isomerize to α-diazonitriles which react carbenically with benzenes by addition, ring-expansion or substitution processes.
