Novel One-pot Synthesis of 1-Iodo-1-trimethylsilyl 1,3-Dienes

Iodine was added to 3-(trimethylsilyl)allylic phosphonium ylide regiospecifically to give 3-iodo-3-trimethylsilyl allylic phosphonium ylide, which reacted with carbonyl compounds to give 1-iodo-1-trimethylsilyl 1,3-dienes with high stereoselectivity in good yield.

A new one-pot synthesis of silylated 1,3-dienes

A new convenient one-pot synthesis of substituted silylated 1,3-dienes starting from the commercial available substances is described.

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.
