The synthesis of methyltrimethylsilane involves the addition of phenyl groups to benzene to give it a higher UV-VIS spectral sensitivity. Aside from being highly reactive, it is also flammable and irritating to the eyes and respiratory system. For this reason, the compound must be handled only in a well-ventilated fume hood. Additionally, proper protective clothing and equipment should be worn while handling the title compound.

The synthesis of methyltrimethylsilane can be performed in a variety of ways. By combining the aldehyde with a cyclic alcohol (benzophenone) and a thiol, it can be used as a solvent in a wide variety of applications. However, this process is not very convenient. To avoid this complication, some people prefer a solvent-free method.

Raman spectrum

The Raman spectra of methyltrimethylsilane were investigated using several different compounds. In addition to the standard trimethylsilane, ethyltrimethylsilane, diethyldimethylsilane, and triethylmethylsilane were also studied. The differences between these compounds were attributed to surface-enhanced effects.

Polyatomic radicals have played a prominent role in astrophysical sources and have only been recognized in the past ten to fifteen years. They have many complicated properties and are more difficult to excite in emission than diatomic molecules. However, the Raman spectrum allows us to study ordinary polyatomic molecules through the Raman effect and infrared absorption. So, how do we interpret the Raman spectrum of methyltrimethylsilane?


The thermal decomposition of ethyltrichloro-silane and ethyltrimethylsilane was studied in the gas phase at 823K. The main primary process involves dehydrosilylation and a radical chain sequence. Several additional products were produced by secondary reactions. These reactions involve a radical chain sequence with the formation of vinyl chloride likely following it.

The reaction takes place at 130 degC for one hour, and the reagents oxalyl chloride, ethyl 4-(trimethylsilyl)-but-2-oxobutenoate, ethylenedimethyl-silane, and ethyl-trimethylsilane are added in varying concentrations. These concentrations are used to determine the chemical composition of the final product.

Synthetic method

The general procedure for the synthesis of methyltrimethylsilane is straightforward: a fresh solution of mercaptoamine is added to a molecule of dichloromethylsilane. The resulting mixture is then subjected to a group exchange reaction, which gives rise to high-purity methyldimethoxysilane. In this way, dichloromethylsilane is converted to methyltrimethylsilane with an impressive utilization rate of 90%.

The reaction proceeds to a silyl dithiolane, an intermediate compound which opens the door to many other silyl heterocycles. The diisopropylethylamine is added to the reaction mixture to produce silyl dimethylsilane 2. The nucleophilic substitution of bromine with a thiol group gives intermediate compound 5a, which is used as an intermediate in subsequent reactions. The thiol group is then replaced with a hydroxyl radical to produce oxathiolane.
