Mass Spectrometry of Allyloxy Di- and Trimethylsilanes
Steele, Kent P.,Weber, William P.
, p. 222 - 228 (1982)
The mass spectra of allyloxydimethylsilanes and allyloxytrimethylsilanes were examined.Isotopic labelling and metastable peaks support the proposed fragmentation patterns.Siliconium ions dominate the spectra.Loss of neutral fragments form + and + ions is important.These fragmentation patterns are discussed in terms of interaction of siliconium ions with the carbon-carbon double bond of the allyloxy ligand.Increased substitution on the allyloxy ligand apparently decreases the interaction of siliconium ions with the carbon-carbon double bond.

Paragraph 0046; 0065; 0077; 0081, (2018/05/30)
The invention relates to a preparation method for hydroxypropyl (butyl) disiloxane. The preparation method comprises the following steps: (1) mixing an allyl alcohol salt-allyl alcohol mixed solution or an alkenyl butyl alcohol salt-alkenyl butyl alcohol mixed solution and hydrogen chlorosilane in an organic solvent, introducing inert gas, stirring the mixture to react, distilling the mixture and collecting a fraction to obtain an alcoholysis product; (2) adding a hydrosilylation catalyst and a co-catalyst into the alcoholysis product, stirring the mixture to react for 4-10 hours, and after reaction, naturally cooling the mixture to room temperature; and (3) adding a hydrochloric acid solution into the product obtained in the step (2), stirring the mixture and carrying out reflux reaction for 5-12 hours, after reaction, naturally cooling the mixture to room temperature, adjusting the pH to neutral, separating liquids to remove a lower solution, washing an organic phase by water to neutral, extracting the organic phase by an extraction agent, removing the extraction agent and drying the mixture to obtain the hydroxypropyl (butyl) disiloxane. The method provided by the invention is high in yield of target product, the highest yield of the alcoholysis product can reach 94.32%, and the highest yield of an addition-hydrolysate can reach 89.58%.

Mechanism of the Reactions of Dimethylsilylene with Oxetanes
Gu, Tai-Yin Yang,Weber, William P.
, p. 1641 - 1644 (2007/10/02)
Dimethylsilylene reacts with oxetane to give high yields of allyloxydimethylsilane and 2,2-dimethyl-1-oxa-2-silacyclopentane.These products result from decomposition of an initial 1,2-zwitterionic intermediate which is formed by coordination of the electrophilic dimethylsilylene with the oxygen of oxetane.Similar results have been obtained from the reactions of dimethylsilylene with 2-methyloxetane, 2,2-dimethyloxetane, 3,3-dimethyloxetane, and 2-vinyloxetane.
