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, Journal of Applied Electrochemistry called Electrochemical reactions of halohydrins. II. Olefins formation, Author is Cipris, D., which mentions a compound: 542-58-5, SMILESS is CC(OCCCl)=O, Molecular C4H7ClO2, Electric Literature of C4H7ClO2.

2-Bromoethanol was reduced to ethylene, 1-bromo-2-propanol to propylene, and 2-bromo-1-indanol to indene on Pb or Cu electrodes with R4N+ electrolytes, in DMF with and without addition of water. Material and current efficiencies were high. H was the only by-product in all cases. This represents a general method for the conversion of bromohydrins to olefins.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《New preparation and some reactions of di(β-chloroethyl) sulfate》. Authors are Suter, C. M.; Evans, Peter B..The article about the compound:2-Chloroethyl acetatecas:542-58-5,SMILESS:CC(OCCCl)=O).Computed Properties of C4H7ClO2. Through the article, more information about this compound (cas:542-58-5) is conveyed.

Distillation of 100 g. (ClCH2CH2)2O and 48.4 g. of SO3 at 2-3 mm. gives 91% (102 g.) of (ClCH2CH2)2SO4 (I), b3 126-9°; if the I is stirred with warm dilute alkali before the 2nd distillation the ester remains water-white indefinitely. Refluxing 20 g. I, 7.5 g. AcONa and 15 cc. AcOH for 1 h. gives 95.5% of ClCH2CH2OAc; BzONa and I, heated 2 h. at 170°, give 61.5% of ClCH2CH2OBz. I (0.112 mol.) and the Grignard reagent from 0.075 mol. PhCH2Cl give 66% of Ph(CH2)3Cl; PhMgBr gives 25% of Ph(CH2)2Cl. Various other reactions are discussed. (BrCH2CH2)2O gives a low yield of I. Attempts to obtain sulfates from Pr2O and (ClCH2CH2CH2)2O gave tarry reaction mixtures which could not be distilled even in a high vacuum.
