Ph 3 P/I - -promoted dichlorination and dibromination of epoxides by using XCH 2 CH 2 X (X = Cl or Br) as the halogen source and reaction solvent is described. All reagents are widely available and easy to handle, and mild conditions and operational simplicity make this protocol attractive.

The reaction of alkenes, chlorine and oxirane, dioxane, ethyleneglycole, oligoethyleneglycoles, the monoethers of oligoethyleneglycoles, ethylene chlorohydrine or α-hydro-ω-chloro-oligooxyethylenes leads to compounds 6-9, which contain mono or oligoether functions and one or two reactive terminal chlorine atoms.Oxathiaalkanes (10 and 12) were obtained in the reaction of such compounds with sodium mercaptides.
Polyfunctionalized N-Tensides. VII. Substitution and Elimination in the Reaction of 1,2-Dihalogenoalkanes with Amines
Beger, J.,Meerbote, E.
, p. 12 - 22 (2007/10/02)
1,2-Dichloroalkanes, 1,2-Dibromoalkanes and mixtures of 1-bromo-2-chloroalkanes and 1-chloro-2-bromoalkanes react with primary or secondary amines and give both elimination and substitution products, often in a nearly 1:1 proportion.The elimination products are the cis and trans-1-halo-1-alkenes, the 2-halo-1-alkenes, the 1,3- and 2,4-dienes and the 1-alkenes.The main substitution products are the 1,2-bis-aminoalkanes.Physical dates, 1H-n.m.r.-spectra,surface tension values and CMC-dates are given.
