Versatile synthesis of 1,1-diaryl-1-alkenes using vinylboronate ester as a platform

A sequence of double Mizoroki-Heck reaction of vinylboronate pinacol ester with aryl halides followed by Suzuki-Miyaura coupling of thus-generated β,β-diarylvinylboronate esters with alkyl halides produces pharmaceutically important 1,1-diaryl-1-alkenes v

Silylalkenes and -dienes via (Silylalkylidene)phosphoranes

The reaction of the (silylalkylidene)phosphoranes 3 and 4 with the ketones 5 - 7 and 16 leads to the silylated olefins 8 - 10 and 17, 18.With fluorenone (11), 3 affords the spiro compound 14, via (silylpropylidene)fluorene 13, which is also obtained by dehydration of 9--9-fluorenol (12).With the ketones 5 - 7 and 11, triphenylphosphorane (20) yields the silylated dienes 21 - 24.From cyclohexane (22) and tetracyanoethene (25) the spiran 26 is formed by cycloaddition.
