    摘要: Mercaptoalkylalkyldialkoxysilane compositions are prepared by reacting an alkoxysilane containing an unsaturated organic group, with a sulfur containing organic acid, in the presence of a peroxide catalyst. This step produces a thiol ester. In the next step, methanolysis of the thiol ester is carried out in the presence of a basic catalyst. The resulting product is a mercaptoalkylalkyldialkoxysilane composition such as mercaptoethylmethyldimethoxysilane, mercaptomethylmethyldiethoxysilane, mercaptopropylmethyldiethoxysilane, or mercaptopropylmethyldimethoxysilane. Carrying out the first step of the reaction at least in part in the presence of air obtains maximum efficiency.

    摘要: Organosilicon aldehydes and ketones are prepared by a method in which an organosilicon compound containing ozonide functionality is first formed by exposing an organosilicon compound containing unsaturation to ozone. The organosilicon compound containing ozonide functionality is then reduced to the corresponding organosilicon aldehyde or ketone with a reducing agent. One preferred reducing agent is a combination of zinc and acetic acid. Complete conversion of the ozonide to the carbonyl (.dbd.C.dbd.O) compound is obtained when the ozonide containing the reducing agent is heated briefly to about 30.degree. C.
