699-18-3 Usage
Uses
Agricultural chemical.
General Description
2-(2-Nitrovinyl)furan (NVF) is a 2-furylethylene derivative with a potential antiprotozoal property. It forms solid inclusion complexes with cyclodextrine (CD) derivatives, 2-hydroxypropyl-β-cyclodextrin and sulfobutyl ether-β-cyclodextrin. The Friedel-Crafts alkylation of naphthols with NVF in aqueous medium and catalyst-free condition has been reported. The formation of Morita-Baylis-Hillman (MBH) adduct via MBH reaction of NVF with diisopropyl azodicarboxylate (DIAD) has been studied.
Safety Profile
A poison by ingestion.
Moderately toxic by inhalation. Mutation
data reported. When heated to
decomposition it emits toxic vapors of NOx.
Check Digit Verification of cas no
The CAS Registry Mumber 699-18-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 699-18:
(5*6)+(4*9)+(3*9)+(2*1)+(1*8)=103
103 % 10 = 3
So 699-18-3 is a valid CAS Registry Number.
InChI:InChI=1/C6H5NO3/c8-7(9)4-3-6-2-1-5-10-6/h1-5H/b4-3+

H-Y zeolite is a versatile heterogeneous catalyst for the synthesis of β-nitroamines
Komura, Kenichi,Taninaka, Yuki,Ohtaki, Yoshifumi,Sugi, Yoshihiro
experimental part, p. 211 - 215 (2011/02/23)
Heterogeneous aza-Henry reactions of aldimes with nitromethane were examined with zeolites as catalysts. Among the zeolite used, H-Y zeolite showed satisfactory catalytic activity for various aldimines, resulting in corresponding β-nitroamines in good yields. H-Y zeolite also showed the excellent reusability until the 3rd usage without loss of its activity; further, the calcination of deactivated H-Y zeolite allowed it to rejuvenate its catalytic activity. Solid-state 13C MAS NMR revealed the predominant activation of an aldimine into the H-Y zeolite.
