- Example 1 was repeated with the modification that the reactants were metered in in a molar ratio of 1: 1.3 silane: allyl chloride mixture. After the crude mixture had been worked up by distillation using a thin-film evaporator to separate off the catalyst and the excess allyl chloride, chloro (3-chloropropyl) dimethylsilane was obtained in a purity of> 99%, based on the silane, in a yield of 95%.
- Example 1 was repeated with the modification that 1x10 " ⁇ mol% di- ⁇ -chloro-bis- [(cycloocta-lc, 5c-diene) -iridium (I)] and lxlO -3 mol% 1, 5- Cyclooctadiene were used after the crude mixture had been worked up by distillation using
- Example 1 was repeated with the modification that toluene was introduced into the reactor as a solvent before the start of metering. After the crude mixture had been worked up by distillation using a thin-film evaporator to separate off the catalyst and the excess allyl chloride, chloro (3-chloropropyl) dimethylsilane was obtained in a purity of> 99%, based on the silane, in a yield of 95%.
- Example 1 was repeated with the modification that a tubular reactor was used instead of the loop reactor. After working up the crude mixture by distillation
- Example 1 was repeated with the modification that instead of a freshly prepared catalyst / cocatalyst mixture, the high-boiling residue obtained when the product was separated off was used. After the crude mixture had been worked up by distillation using a thin-film evaporator to separate off the catalyst and the excess allyl chloride, chloro (3-chloropropyl) dimethylsilane was obtained in a purity of> 99%, based on the silane, in a yield of 95%.
