HPLC of Formula: 17190-29-3. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 3-Hydroxy-3-phenylpropanenitrile, is researched, Molecular C9H9NO, CAS is 17190-29-3, about 1,3-Dipolar cycloadditions. 72. Reactions of fulminic acid with unsaturated compounds.
The slow generation of fulminic acid (I), the parent substance of nitrile oxides, from ICH:NOH and NEt3 in organic media makes in situ cycloadditions to alkenes and alkynes of sufficient dipolarophilic activity possible. The NMR spectra allow the structural elucidation of the produced 2-isoxazolines and isoxazoles. The observed directions of cycloaddition correspond largely to those of benzonitrile oxide. On using dipolarophiles of lower activity, the oligomerization of formonitrile oxide competes with its cycloadditions; in some cases cycloadducts of the dimeric I HON:CHC:N+O- were isolated. The so far nearly unknown 2-isoxazolines unsubstituted in 3-position suffer a base-catalyzed ring opening which leads to the formal adducts of OH and CN to the double bond of the olefinic dipolarophile. Free I is not an intermediate in the formation of PhNHCOCN+O- from MeNO2 and PhNCO in the presence of NEt3 as shown by competition experiments
