CA 2132205

2132205 9319034 PCTABS00025 Production of chlorine-substituted olefine compounds of formula (I), wherein: R1 represents a C-organic rest; R2 represents -CN, -CO-R3, -CO-S-R3, -CO-O-R3, -CO-N(R4, R5); R3 represents a C-organic rest; R4, R5 represent H, C-organic rest. The process is bared on the reaction of oxiranes of formula (II) in the presence of a carboxylic acid amide (IIIa) or a lactam (IIIb) in the liquid phase with a chlorinating agent of formula (IV). Process products of formula (I) are important intermediate products for the production of dyes, pharmaceuticals and plant-protecting agents.
