The thermolysis of some 1,1-di- or 1,1,2-tri-substituted 1-silacyclobutanes leads to 1,3-disilacyclobutanes or to polymeric products.A possible intermediate silaalkene could not be stabilized, even in the presence of bulky substituents at the silicon atom.Photolysis of some di- or tri-substituted silacyclobutanes in methanol results in ring opening or in elimination of an alkene with further reaction of the intermediates with the solvent.Photolysis of the 1,1-diphenyl-2-methyl-1-silacyclobutane in cyclohexane leads to the 1,1,3,3-tetraphenyl-1,3-disilacyclobutane.The influence of the substituents at the silicon or the carbon atom on the reaction pathways is discussed.Photolysis opening and addition of methanol, whereas the 1,1,3,3-tetraphenyl-1,3-disilacyclobutane does not show any reaction.

An efficient chemoselective iridium-catalyzed method for the hydroxylation and alkoxylation of organosilanes to generate hydrogen gas and silanols or silyl ethers was developed. A variety of sterically hindered silanes with alkyl, aryl, and ether groups were tolerated. Furthermore, this atom-economical catalytic protocol can be used for the synthesis of silanediols and silanetriols. A one-pot silane oxidation and chemoselective reduction of aldehydes/ketones was also realized.

Paragraph 0048, (2017/03/14)
The invention relates to a method for synthesizing phenyl methyl dialkoxyl silane with high selectivity. The structural formula of phenyl methyl dialkoxyl silane is PhMeSi(OR)2, in which R is alkyl with 1-6 carbons. The method is characterized by comprising the following steps of: performing reaction with methyl trialkoxyl silane based on non-cyclic ether compounds such as ethyl ether as a reaction liquor and a bromobenzene Grignard reagent as a raw material; and then, obtaining the target compound, i.e., phenyl methyl dialkoxyl silane with high selectivity and high yield through simple filtering and fractional purification, and meanwhile, greatly inhibiting the generation of a byproduct diphenyl methyl alkoxyl silane.
