The facile 1,4-migration of Pd between a vinylic position and an arene and between the ortho positions of biaryl compounds have recently been reported. Aryl to benzylic and alkyl to aryl Pd migrations are also known. Herein we report a novel, consecutive vinylic to aryl to allylic Pd ...
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...
the Skrydstrup group elegantly succeeded the catalytic carbonylation of primary benzylic electrophile using a nickel pincer complex with a CO-gen precursor via the slow addition of Negishi reagent to circumvent the direct Negishi coupling, although the use of allyl electrophiles received limited success ...
6.3.6.3.2 Epoxidation of vinyl allenic alcohols Since epoxidation at the vinyl double bond is unproductive, it is desirable to direct reaction on the allene moiety. This can be accomplished by taking advantage of the hydroxy-directed epoxidation of allylic alcohols using the t-butyl hydroperoxide/...
