Chlorosilanes are utilized in hydrosilation where the addition of a SiH compound to a multiple bond, often an
alkene or alkyne, is the pathway to synthesizing a veriety of unique polysiloxane systems.
Alkenes and especially alkadienes as well as compounds with heteroatom play an important role in the forming of deposits.
The formation of aromatic hydrocarbons was proposed to involve the following conversions: cracking of large aliphatic hydrocarbons to yield low-molecular-weight (LMW) alkanes and
alkenes, which is catalyzed by the strongly acidic sites in Co[Cl.sub.2] 6[H.sub.2]O and Ni[Cl.sub.2] 6[H.sub.2]O, cyclization of LMW
alkenes and dialkenes to form cyclic
alkenes, and dehydrogenation of cyclic
alkenes to yield aromatic hydrocarbons [22].

alkenes with Methylosinus trichosporium (OB3b)," Journal of Molecular Catalysis, vol.
Epoxides are an important class of compounds in many industrial processes and often made by the epoxidation of
alkenes [1].
Electropolymerizable compositions include 1,1-disubstituted
alkene compounds, acid stabilizers and free radical stabilizers.
Alkene and reactive free radicals derived from thermal pyrolysis could be oxidized to form acid oxygen-containing compounds (peaks 11, 12, 31, 36, and 43), which lead to increasing acid number.
Components were also found in these categories:
alkenes, aldehydes and ketones, esters, and ethers (small amounts).
Partial hydrogenation of alkyne to the corresponding
alkene by functionalized Si-MCM-41/ metformin/ palladium catalyst 120 mg prepared catalyst mixed in 100 cc methanol was poured in a flask and 20 mmol alkyne was added to this mixture.
All of the available data and observations are consistent with our notions and belief that the reaction involves Al-promoted carbozirconation of
alkenes in accord with widely accepted mechanistic insights in the area of the Ziegler-Natta
alkene polymerization.
