Die photoinduzierte umsetzung der tricarbonyl-hydridkomplexe Cp′W(CO)3H (Cp′ = η5-C5H5, η5-C5Me5) mit methylacetylen und dimethhylacetylen zu η3-allyl- und metallacyclischen alkenylketon-komplexen. Molekülstruktur von C5Me5W(CO)2(η3-C3H5)

摘要: Abstract The photo-induced reaction of the hydrido complexes Cp′W(CO)3H (Cp′ = η5-C5H5, η5-C5Me5) with methylacetylene and dimethylacetylene gives η3-allyl Cp′W(CO)2(η3-C3H5) Cp′W(CO)2(η3-C4H7) metallacyclic alkenylketone complex C5Me5 W(CO) 2 [MeCCHC(O) CHCHMe]. Phenylacetylene C5Me5W(CO)3H react in tetrahydrofuran solution under photochemical conditions to give substitution product C5Me5W(CO)2(thf)H. crystal structure C5Me5W(CO)2(η3-C3H5) is described.
