发明名称 Method of preparing halogenoalkyldialkyl chlorosilane
摘要 3-Chloropropyldimethylchlorosilane is prepared by hydrosilylation reaction in a reaction medium comprising dimethylhydrochlorosilane and allyl chloride, in the presence of a catalytically effective amount of di-p-chlorobis(eta-1,5-cyclooctadiene)diiridium and wherein at least one auxiliary in the free or supported state selected from the group of compounds consisting of: (i) ketones, (ii) ethers, (iii) quinones, (iv) anhydrides, (v) unsaturated hydrocarbon compounds (UHC) whether aromatic and/or comprising at least one C-C double bond and/or at least one C≡C triple bond, it being possible for these unsaturated bonds to be conjugated or nonconjugated, the said UHCs being linear or cyclic (mono- or polycyclic), having from 4 to 30 carbon atoms, having from 1 to 8 ethylenic and/or acetylenic sites of unsaturation and optionally comprising one or more heteroatoms, and (vi) mixtures thereof, is added to the reaction medium, with the proviso that, when the auxiliary comprises one or more UHCs as defined above, then this (these) UHC(s) is (are) mixed with at least one other auxiliary other than a UHC.
