768-16-1 Usage
General Description
5-Nitrobicyclo[2.2.1]hept-2-ene is a chemical compound with the molecular formula C7H9NO2. It is a bicyclic compound containing a nitro group and a double bond in its structure. 5-Nitrobicyclo[2.2.1]hept-2-ene has a bicyclo[2.2.1]heptane backbone, which consists of two fused cyclopropane rings and one cyclopentane ring. The presence of the nitro group makes this compound highly reactive and potentially explosive. It is used in organic synthesis and as a precursor in the production of various pharmaceuticals and agrochemicals. However, it should be handled with caution due to its explosive nature.
Check Digit Verification of cas no
The CAS Registry Mumber 768-16-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 768-16:
(5*7)+(4*6)+(3*8)+(2*1)+(1*6)=91
91 % 10 = 1
So 768-16-1 is a valid CAS Registry Number.

Trimethylsilyl Nitronates Derived from 2-Substituted Nitroethanes in δ-Elimination Reactions
Ioffe, S. L.,Makarenkova, L. M.,Strelenko, Yu. A.,Tartakovskii, V. A.

Silylation of β-substituted nitroethanes XCH2CH2NO2 (X=Cl or OCOCH3) with conventional silylating agents yields corresponding trimethylsilyl nitronates which undergo δ-elimination of nitroethylene under the reaction conditions.Stable silyl nitronates containing one or two trimethylsilyl groups were isolated in the silylation of C6H5NHCH2CH2NO2. 1,3-Dipolar cycloaddition of the nitronates to methoxide ion results in formation of 5-methoxycarbonyl-3-phenylaminomethyl(or 3-N-trimethylsilylphenylaminomethyl)-3-trimethylsiloxyisoxazolidines.Thermolysis of the latter affords 5-methoxycarbonyl-2-isoxazoline.
