olefinic การใช้

• Those olefinic gases are valuable for use as petrochemical feedstocks.
• Deprotonated acyclic ethers perform beta-hydride eliminination, forming an olefinic ether.
• Cyanamide adds itself in the presence of N-bromosuccinimide to olefinic double bonds.
• All the drug molecules are made only after the two olefinic double bonds have been reduced.
• The Schreiber team recognized three fragments of roughly equal complexity that are separated by olefinic units in discodermolide.
• The formed hydride then attacks the olefinic rest in ? position to the ether oxygen, releasing the alkoxide.
• All trichothecenes contain a common 12, 13-epoxytrichothene skeleton and an olefinic bond with various side chain substitutions.
• Carbonyl groups, olefinic fragments and aromatic rings contribute " sp 2 " hybridized carbon atoms to an aliphatic chain.
• The carbon of diazomethane bears the largest HOMO orbital, while the terminal olefinic carbons of methyl acrylate and styrene bear the largest LUMO orbital.
• The gasoline produced in the FCC unit has an elevated octane rating but is less chemically stable compared to other gasoline components due to its olefinic profile.
• In organic synthesis palladium cyanide is used in the synthesis of olefinic cyanides from olefins . and as a catalyst in the regioselective reaction between cyanotrimethylsilane and oxiranes.
• The first was the addition of polyhalogen compounds to olefins, was found during Prins doctoral research, while the others, the acid-catalyzed addition of aldehydes to olefinic compounds, became of industrial relevance.
• Once the 2-methylthiazole ring has been made, it is then transferred to the PKS EPOS B ( epoB ), EPOS C ( epoC ), EPOS D ( epoD ), EPOS E ( epoE ), and EPOS F ( epoF ) for subsequent elongation and modification to generate the olefinic bond, the 16-membered ring, and the epoxide, as seen in "'Figure 5 " '.
• Rxn of " p "-fluorobenzyl chloride ( "'1 "') with the anion of diethylmethyl malonate ( "'2 "') gives intermediate diester ( "'3 "'), saponification of which and subsequent decarboxylation leads to "'4 "'. { Alternatively it can be formed by Perkin reaction between p-fluorobenzaldehyde and propionic anhydride in the presence of NaOAc, followed by catalytic hydrogenation of the olefinic bond using a palladium on carbon catalyst .}
