3,4-Dichloro-1-butene → HCID 10999815, compound

596 g trichlorosilane (4.4 moles, excess) and 500 g 3,4-dichlorobutene-1 (4 moles) are mixed. 0.4 g Pt(II)-acetyl acetonate are added to 30 ml of this mixture, at which time the temperature gradually rises by itself to 95° C. At this temperature, the remaining trichlorosilane/olefin mixture is added and allowed to react for an additional half hour at 92° C. Excess trichlorosilane and other readily volatile constituents are drawn off in a vacuum. The crude product obtained in this manner (826 g ≅79.3 % of theory) is subsequently purified by distillation. 705 g 3,4-dichlorobutyl trichlorosilane≅7 % of theory are obtained as the main fraction (see table 1 for composition data).
