We report on the first example of a transition metal-catalyzed cyclohex-1-enyl, isopropenyl, methoxymethyl, 1-trimethylsiloxycyclohex-1-yl) in the presence of catalytic amounts of cyclization reaction of a Fischer carbene complex. It comprises the generation of vinyl-and divinyl cyclopentadienes und
