Abstract

Treatment of the vinylacetylide complex Cp* WRe₂(CO)₉[C≡CC(Me)=CH₂] (1) with alcohols and with dihydrogen in refluxing toluene solution afforded allenylidene complexes Cp*WRe₂(CO)₈(μ-OR)(C=C=CMe₂), R = Me (2a), R = Et (2b), and R = Ph (2c), and formally unsaturated metallacyclopentadienyl complexes Cp*WRe₂(CO)₇(μ-H)[CHCHC(Me)CH] (3a,b), respectively. Evidence of fluxionality of allenylidene complexes 2 in solution is presented.
