A useful extension of sulfoxide–sulfenate rearrangements exploits the greater stability of allylicvs.vinylic sulfoxides.127For example, the Knoevenagel product (202) is deconjugated under the conditions of its formation. This sets the stage for a 2,3-rearrangement in the same pot (equation66)....
Disclosed is a process for preparing copolymer dispersions made of alkylene oxides and glycidyl ethers according to formula (I) in which R1 is hydrogen or a C1-C4-alkyl radical, R2 and R4 are an alkyl or aryl radical having 1 to 30 carbon atoms, and R3 i

The reaction was exposed to a wide range of aromatic-, heteroaromatic-, vinylic-, and aliphatic-substituted allylic phosphates to deliver the corresponding allyl isonitriles in good to excellent yields. Sign in to download full-size image Scheme 47. Palladium catalyzed allylic isocyanation by Oh...
Transition metal-catalyzed carbonylation with carbon nucleophiles is one of the most prominent methods to construct ketones, which are highly versatile motifs prevalent in a variety of organic compounds. In comparison to the well-established palladium catalytic system, the nickel-catalyzed carbonylative cou...
Transition metal-catalyzed enantioselective allylic substitution has emerged as one of the most useful and reliable transformations for precise stereo- and regiocontrol over a target compound in organic synthesis1,2,3,4,5,6. The constructed carbon−carbon or carbon-heteroatom stereocenter vicinal to...
