Alkenyltriphenylbismuthonium salt

Alkenyltriphenylbismuthonium salts are formed by refluxing triphenylbismuth difluoride BF3 OEt2 and alkenyl-trimethylsilanes (Scheme 22).247... [Pg.920]

The reaction of alkenyltriphenylbismuthonium salt with ethyl acrylate in the presence of Pd(OAc)2 (2 mol%) afforded both alkenylated and phenylated products in low yields (Scheme 4) [13]. In addition, ligand coupling products of the bismuthonium salt were also formed. [Pg.202]

Reaction of 1-alkenyltriphenylbismuthonium salts (85) with potassium ferf-butoxide led to the carbene derivatives, 1-alken-l-ylidenes, which can either be trapped by styrene to give cyclopropanes or isomerise to give the corresponding acetylenes. ... [Pg.182]
