Allenylsilver compounds

Allenylsilver compounds appear to enter the palladium coupling catalytic cycle via transmetallation. It was found that tert-butyl allenylsilver, and the corresponding argentate derivative, underwent palladium-catalyzed coupling with iodobenzene to... [Pg.16]

Allenylsilveifl) compounds are prepared in situ by deprotonation of the allenic hydrocarbon with n-butyllithium and subsequent treatment with silver bromide (equation 5). Allenylsilver compounds afford allenic derivatives when treated with a variety of electrophiles, without significant isomerization to the propargyl system (equation Reaction of the allenylsilver compound with carbon disulfide results in an interesting transformation to p, y-unsaturated-7-dithiolactones presumably by way of silver salts (Scheme 11). - ... [Pg.85]
