CONVERSION OF SOME ALKENYLTRIMETHYLSILANES INTO SILYL ENOL ETHERS
Cunico, Robert F.
, p. C51 - C53 (1981)
The cycloaddition products (5-trimethylsilylisoxazolines) between alkenyltrimethylsilanes and acetonitrile oxide undergo thermolytic rearrangement-cycloreversion to afford silyl enol ethers of retained stereochemistry vs. the starting alkenylsilanes.
Efficient room-temperature O-silylation of alcohols using a SBA-15-supported cobalt(II) nanocatalyst
Rajabi, Fatemeh,Luque, Rafael,Serrano-Ruiz, Juan Carlos
, p. 1823 - 1828 (2012/10/29)
The O-silylation of OH groups of alcohols and phenols with hexamethyldisilazane (HMDS) was achieved in high-to-excellent yields using catalytic quantities of a SBA-15-supported cobalt(II) nanocatalyst (typically 0.5 mol-%) at room temperature and under solvent-free conditions. Furthermore, the heterogeneous catalyst showed an excellent durability and can be conveniently reused by filtration for at least twelve times without any noticeable loss of activity. Copyright

Example 2, (2008/06/13)
A method for making a vinyl carbonate represented by the formula (I): CH2═CHOC(O)X1R1??(I) wherein X1is oxygen or sulfur and R1is a substituted or an unsubstituted aliphatic alkyl, aryl, aryl alkyl, olefinic, vinyl, or cycloaliphatic group comprises: (a) reacting a compound represented by the formula (II): X2C(O)X1R1??(II) ?wherein X2is a halogen other than fluorine, with a compound represented by the formula (III): M1—F??(III) ?wherein M1is selected from a Group IA metal, in the presence of a first phase transfer catalyst and a first organic solvent, to form a compound represented by the formula (IV): FC(O)X1R1??(IV) and (b) reacting a compound represented by the formula (IV) with a compound represented by the formula (V): CH2═CHOSi(R2)3??(V) ?wherein R2is a substituted or an unsubstituted aliphatic alkyl, aryl, aryl alkyl olefinic, vinyl, or cycloaliphatic group, or any combination thereof, in the presence of a metal salt represented by the formula M2—F wherein M2is a Group IA metal, a second phase transfer catalyst, and a second organic solvent, to form the compound represented by formula (I).
