We present a new method for the selective C(sp 3)-H cyanation of adamantane derivatives with PINO as the hydrogen abstracting reagent. A cyano radical is thereby transferred from p - toluenesulfonyl cyanide, allowing the cyanation of adamantane derivatives in up to 71% yield. The protocol presents a novel way to orthogonally functionalized adamantanes that are otherwise difficult to prepare. Mechanistic studies support the hypothesis of a radical pathway.
Corresponding amine nitrile and method of manufacturing thereof
-
, (2018/07/15)
The invention relates to a preparation method of nitrile. Compared with the prior art, the preparation method has the characteristics of obvious reduction of the usage amount of ammonia sources, low environmental pressure, low energy consumption, low production cost, high purity and yields of nitrile products, and the like, and can be used for obtaining nitrile with a more complex structure. The invention also relates to a method for preparing corresponding amine with nitrile.

The reaction of 1,3-adamantanedicarbonamide with chlorocarbonylsulfenyl chloride in hot toluene gives two new oxathiazolone derivatives that have had their structures confirmed crystallographically: 1,3-bis(1,3,4-oxathiazol-2-on-5-yl)-adamantane and 1-cyano-3-(1,3,4-oxathiazol-2-on-5-yl)-adamantane. (Crystal data: C10H14(COC(O)SN)2: P21/m, a = 10.447(2), b = 7.119(3), c = 10.684(2) Angstroem, β = 112.98(1) deg, V = 731.5(3) Angstroem3, z = 2, Dc = 1.536 g cm-3, R = 0.034, Rw = 0.029; (NC)C10H14(COC(O)SN): P21/c, a = 9.153(2), b = 19.134(2), c = 7.130(3) Angstroem, β = 105.38(2) deg, V = 1204(1) Angstroem3, z = 4, Dc = 1.447 g cm-3, R = 0.038, Rw = 0.035).The reaction of the precursor with dimethyl acetylenedicarboxylate (DMAD) in refluxing chlorobenzene gave a mixture that was resolved into pure compounds by Kugelrohr sublimation; these were shown to be sulfur, tetramethyl thiophenetetracarboxylate, 1,3-adamantanedinitrile, 1,3-bis(4,5-bis(methoxycarbonyl)-isothiazol-3-yl)-adamantane, and 1-cyano-3-(4,5-bis(methoxycarbonyl)-isothiazol-3-yl)-adamantane.The structures of the two new isothiazole derivatives were confirmed crystallographically. (Crystal data: C10H14(CNS*DMAD)2: Pca21, a = 15.857(4), b = 11.562(4), c = 13.602(4) Angstroem, V = 2494(2) Angstroem3, z = 4, Dc = 1.424 g cm-3, R = 0.057, Rw = 0.038; C10H14(CN)(CNS*DMAD): P21/c, a = 19.683(2), b = 11.566(3), c = 7.727(3) Angstroem, β = 93.30(2) deg, V = 1756(1) Angstroem3, z = 4, Dc = 1.363 g cm-3, R = 0.079, Rw = 0.076).The pattern of reactivity indicates that the synthetic equivalent of the bis(nitrile sulfide) may be present in solution but has a very short lifetime and failed to react at all with 1,3-adamantanedinitrile.Key words: oxathiazolone, nitrile sulfide, cycloaddition, isothiazole.
