(Z)-2-Brom-1-phenylcyclopropancarbonsaeureaethylester, also known as (Z)-2-bromo-1-phenylcyclopropanecarbonylurethane, is an organic compound with the chemical formula C12H13BrNO2. It is a derivative of cyclopropanecarbonylurea, featuring a bromine atom at the 2-position and a phenyl group at the 1-position. (Z)-2-Brom-1-phenylcyclopropancarbonsaeureaethylester is characterized by its unique structure, which includes a cyclopropane ring, a carbonyl group, and an ethyl ester group. It is synthesized through various chemical reactions and is used in the preparation of pharmaceuticals and other organic compounds due to its reactivity and structural properties. The (Z)-isomer indicates the geometric arrangement of the double bond, which in this case, is in the Z configuration, meaning the higher priority substituents are on the same side of the double bond.

Check Digit Verification of cas no

The CAS Registry Mumber 66078-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,0,7 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66078-17:
(7*6)+(6*6)+(5*0)+(4*7)+(3*8)+(2*1)+(1*7)=139
139 % 10 = 9
So 66078-17-9 is a valid CAS Registry Number.

Deamination Reactions, 45. Decomposition of 1-Arylcyclopropanediazonium Ions

Kirmse, Wolfgang,Rode, Jutta

, p. 3694 - 3703 (2007/10/02)

1-Arylcyclopropanediazonium ions have been generated by alkaline cleavage of the analogous nitrosocarbamates in methanol.With increasing ?-donor capacity of the aryl groups, retention of the three-membered ring was enhanced while the stereoselectivity (as probed with the aid of 2-D labels) was diminished or entirely lost (4-methoxyphenyl).Where applicable, the stereoselectivity of ring opening is inferior to that of nucleophilic displacement.The data may be interpreted in terms of competing reactions (ks, kc, kΔ) of the cyclopropanediazonium ions.
