Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Zhurnal Obshchei Khimii called The problem of the structure of Gustavson’s hydrocarbon, Author is Slobodin, Ya. M.; Shokhor, I. N., which mentions a compound: 3229-00-3, SMILESS is BrCC(CBr)(CBr)CBr, Molecular C5H8Br4, Computed Properties of C5H8Br4.

Contrary to Murray and Stevenson (C.A. 38, 1476.9, 3615.1), the Raman spectrum of the hydrocarbon first obtained by Gustavson (J. prakt. Chem. 54, 98, 105(1896)), if it is synthesized by the action of Zn dust on (CH2Br)4C in 80-85% alc., and the product is immediately removed from the reaction mixture (to avoid secondary reactions), then distilled several times (last 2 times over Na), resulting in b. 39-41°, n20D 1.41847, d204 0.7377, MRD 23.25, shows neither the frequency 581 nor 1033 cm.-1, and contains neither spiropentane nor other hydrocarbons with a (CH2)3 ring. By its Raman spectrum, it is a mixture of methylcyclobutane and 2-methyl-1-butene. The presence of small amounts of isoprene is probable. The formation reaction can be represented by C(CH2Br)4 → CH2.CH2.CH2.C:CH2 → CH2CHCME:CH2 +H2 → MeCH2CH2CMe:CH2.

cf. C.A. 44, 7601e. The dipole moments of pentaerythritol tetrabromide (I), tetraiodide (II), and tetranitrate (III) in benzene and in dioxane were determined For both I and II, the dipole moment was zero; this indicates that there is no free rotation about the C-C bond. In the case of III the moment was 2.5 D.; this indicates free rotation about the C-O bond in the nitrate. It is concluded, therefore, that the shortening of the C-O bond, observed in the crystal, cannot be due to a high degree of double-bond character.

In the present work, we have established a novel and environmentally benign method, whereby a 1,3-dipolar cycloaddition reaction was applied using a non-toxic reagent, iodosobenzenediacetate [PhI(OAc)2], instead of the conventional copper-based reagents for the development of star-branched polymers. Here we have demonstrated the synthesis of core cross-linked star (CCS) polymers via the formation of isoxazoline ring using ‘click reaction’ between acrylate functionalities in a polymer chain and in situ generated nitrile oxide groups from a cross-linker added externally. In the initial step, a well-defined styrenic block copolymer with acrylate-functionalized middle-block was synthesized by controlled radical polymerization (RAFT) using α,α’-xylyl-bis(dithiobenzoate) as a chain transfer agent using 4-vinyl benzyl chloride and styrene as comonomers. Thereafter, the chlorobenzyl groups were converted into acrylate by reaction with acrylic acid. In the following step, core cross-linked star (CCS) polymers were synthesized by reacting the above block copolymer and oxime-functionalized cross-linkers (bi- and tetra-functional) using PhI(OAc)2 ‘click chem.’. Formation of CCS polymers was confirmed from NMR, FTIR, GPC and DLS studies.
