Substances of the type MeCH[(CH2)n1X][(CH2)n2R], where n1 or n2 = 0 or an integer, X = a functional group and R = a normal alkyl, Ph or C6Hn group, can be classified into 2 categories, viz., those, typified by X = CHO, in which the configuration of the 1st members having n1 = 0 can be correlated by classical methods to those having n1 > 0, and those, typified by X = halogen, in which such correlation cannot be accomplished by classical methods. For the purpose of solving the latter problem the azides were chosen over the halides, inasmuch as they can be converted into the corresponding amines. The amines, while belonging to the 2nd category, can be correlated among themselves by a sufficiently reliable though nonclassical argument which will be reported later. The secondary azides were prepared by the action of NaN3 on the iodides and the amines by reduction of the azides with PtO2. The rotatory phenomena observed in the series of azides and halides were compared with those in the series of aldehydes and were found to be dissimilar in both series. Hence a comparison of these phenomena cannot be used for the correlation of the members of the series of halides and azides having n1 = 0 with those having n1 > 0. The following compounds were prepared: l-2-iodobutane, b. 111-18°, [M]D25 -24.1°, from the alc. and anhydrous HI in a bomb tube at room temperature for 2 days; d-2-azidobutane, b500 85°, d425 0.8619, nD25 1.4122, [M]D25 15.9°; d-2-aminobutane, [M]D25, 0.66° (in H2O), (HCl salt, [M]5875.625 -0.44° (in H2O)); l-2-iodoöctane, b1 52°, nD25 1.4863, d425 1.3158, [M]D25 -80.0°; d-2-azidoöctane, b9 68°, nD25 1.4332, d425 0.8555, [M]D25 43.4°, 42.5° (in heptane (I)); d-2-aminoöctane, b9 48°, nD25 1.4220, [M]D25 5.41°, (HCl salt, [M]D25 -6.44° (in H2O)); d-1-iodo-2-methylbutane, b. 145-6°, nD25 1.4950, [M]D25 8.28°, maximum [M]D25 11.1°; d-1-azido-2-methylbutane, b138 72°, nD25 1.4240, d425 0.8770, [M]D25 8.61°, maximum [M]D25 11.6°; l-1-amino-2-methylbutane, b12 40-5°, [M]5875.625 -0.21° (in H2O); l-1-azido-2-methylhexane, b15 59-60°, [α]D25 -0.30°; d-1-iodo-2-methylnonane, b4 86°, d425 1.254, [M]D25 2.54°; l-1-azido-2-methylnonane, b10 98-102°, d425 0.8658, nD25 1.4430, [M]D25 -0.74°; l-1-iodo-3-methylpentane, b12 54°, d425 1.3934, nD25 1.4866, [M]D25 -16.1°, maximum [M]D25 -43.9°; l-1-azido-3-methylpentane, b. 145-8°, nD25 1.4300, [M]D25 -9.63°, maximum [M]5875.625 -26.3° (in I); d-1-iodo-4-methylhexane, b13 74-5°, b103 124-6°, nD25 1.4852, d425 1.3579, [M]D25 8.20°, maximum [M]D25 26.2°; d-1-azido-4-methylhexane, b418 157°, d425 0.8636, nD25 1.4323, [M]5875.625 5.41°, maximum [M]5875.625 17.3° (in I.).

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Analysis of rotatory dispersions of configurationally related halides, published in 1936, which mentions a compound: 616-14-8, Name is 1-Iodo-2-methylbutane, Molecular C5H11I, Synthetic Route of C5H11I.

Rotatory dispersion curves of halides of the type HMeRC(CH2)nX (X = Cl, Br, I; R = alkyl group; n = 0, 1, 2 or 3) are analyzed in the visible and the ultraviolet regions. The 3 halogen atoms function similarly with respect to the character of this curve in compounds of identical structure. A periodicity in the sign of some of the partial contributions of the halogen atom occurs with increase in n. The course of the rotatory dispersion when n = 1 is anomalous. An attempt is made to apply results when n > 0 to the sign of rotation for compounds where n = 0. When X = COOH, CHO, CN, CHMe2, etc., no complete analogy exists between this group and the group where X is a halogen. [M]D25 maximum (homogeneous) is given for the 16 compounds where X = Br, n = 1, 2, 3, 4, and R = Et, Pr, Bu, pentyl, and for the compound HMeEtC(CH2)5Br. Absorption spectra are given for λ 2100-3300 for 5 iodides. Rotatory dispersion curves are given for the compounds HMeEtCCH2I, HMe(C6H13)CCH2I, HMeEtCCH2Br and HMeEtCCH2Cl. [M]D25 maximum, nD25, d425 (vacuum) and rotatory dispersions (numerical) are given for several other compounds in this series. Differences between the interpretation of the dispersions of the iodides given by the authors (C. A. 27, 951) and that given by Kuhn (C. A. 29, 7159.1) are due to substantial differences between their exptl. data.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Optical rotations of configurationally related azides, published in 1936, which mentions a compound: 616-14-8, mainly applied to , Application of 616-14-8.

Substances of the type MeCH[(CH2)n1X][(CH2)n2R], where n1 or n2 = 0 or an integer, X = a functional group and R = a normal alkyl, Ph or C6Hn group, can be classified into 2 categories, viz., those, typified by X = CHO, in which the configuration of the 1st members having n1 = 0 can be correlated by classical methods to those having n1 > 0, and those, typified by X = halogen, in which such correlation cannot be accomplished by classical methods. For the purpose of solving the latter problem the azides were chosen over the halides, inasmuch as they can be converted into the corresponding amines. The amines, while belonging to the 2nd category, can be correlated among themselves by a sufficiently reliable though nonclassical argument which will be reported later.
