Purification Methods
Fractionally distil 1-nitronaphthalene under reduced pressure, then crystallise it from EtOH, aqueous EtOH or heptane. Chromatograph it on alumina with *benzene/pet ether as eluent. It sublimes in vacuo. The 1:1 picrate complex has m 72o (from EtOH). [Beilstein 5 H 553, 5 III 1593, 5 IV 1673.]
Check Digit Verification of cas no
The CAS Registry Mumber 86-57-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 86-57:
(4*8)+(3*6)+(2*5)+(1*7)=67
67 % 10 = 7
So 86-57-7 is a valid CAS Registry Number.

Photoinduced Iron-Catalyzed ipso-Nitration of Aryl Halides via Single-Electron Transfer

A photoinduced iron-catalyzed ipso-nitration of aryl halides with KNO2 has been developed, in which aryl iodides, bromides, and some of aryl chlorides are feasible. The mechanism investigations show that the in situ formed iron complex by FeSO4, KNO2, and 1,10-phenanthroline acts as the light-harvesting photocatalyst with a longer lifetime of the excited state, and the reaction undergoes a photoinduced single-electron transfer (SET) process. This work represents an example for the photoinduced iron-catalyzed Ullmann-type couplings.
Microwave-induced surface-mediated highly efficient regioselective nitration of aromatic compounds: Effects of penetration depth
BANIK, BIMAL K.,DAS, APARNA,YADAV, RAM NARESH
, p. 2203 - 2206 (2021/08/24)
Surface mediated highly regioselective nitration of aromatic compounds under diverse microwave-induced conditions was investigated in this work. The effects of the penetration depth of the surfaces were found to be more crucial than other dielectric parameters. Despite significant progress of microwave-induced reactions, no reports have examined the penetration depth of the surfaces used in these processes.
