General Description
1-(Bromomethyl)-4-methylidenecyclohexane is a chemical compound with the molecular formula C8H13Br. It is a cyclic compound with a six-membered ring and a bromomethyl group attached to one carbon atom. The compound also contains a double bond, giving it a degree of unsaturation. The presence of the bromine atom makes it a halogenated compound, which can have various applications in organic synthesis, pharmaceuticals, and material science. Due to its structural complexity, 1-(Bromomethyl)-4-methylidenecyclohexane may have potential uses in the development of new drugs or materials. However, it is important to handle this compound with care, as bromomethyl groups are known to be reactive and potentially hazardous.
Check Digit Verification of cas no
The CAS Registry Mumber 76825-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,2 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76825-09:
(7*7)+(6*6)+(5*8)+(4*2)+(3*5)+(2*0)+(1*9)=157
157 % 10 = 7
So 76825-09-7 is a valid CAS Registry Number.

Synthesis of Bridgehead-Substituted Bicycloheptanes by Radical Cyclization
Della, Ernest W.,Knill, Andrew M.,Pigou, Paul E.
, p. 2110 - 2114 (2007/10/02)
A kinetic investigation shows that the rate of cyclization (kC) of the (4-methylenecyclohexyl)methyl radical 3 at 25 deg C is 4.4 x 102 s-1, which is considerably slower than that (2.3 x 105 s-1) of the parent 5-hexenyl radical.The energy of activation for the process 3 -> 4 is 12.8 kcal mol-1, which is in excellent agreement with theoretical values derived from force-field calculations.Ring-closure of appropriately substituted (4-methylenecyclohexyl)methyl radical precursors allows the synthesis of bicycloheptyl systems with useful functionality at the bridgehead to be achieved readily and in high yield.An interesting example is given of the application of an iodine-atom-transfer cyclization to the synthesis of a bicycloheptane functionalized at C7 and C1.
