%X Treatment of
CpW(CO)2(η4-cyclohexadiene)BF4 with RMgBr (R = methylvinyl, phenyl,
naphthyl)
in cold THF (−78 °C) afforded the
CpW(CO)2[(1,2,4-η)-1-CO-2-R-cyclohexene] complex as the major product;
this result provides an example of a nucleophile attacking the internal carbon of a cationic η4-diene
fragment.
