- 中文摘要: Known to be a facile irontricarbonyl transfer reagent,(.eta./sup 2/-cis-C/sub 8/H/sub 14/)/sub 2/Fe(CO)/sub 3/(1) transfers its Fe(CO)/sub 3/ unit to a variety of ligands at low temperature. Stirring a THF mixture of (1) and PhC.ident.CPh under N/sub 2/(g) at -60.degree.C for 1h then at room temperature overnight provides mainly a flyover- bridge product [ -CPh=CPhC(O)-CPh=CPh- ] Fe/sub 2/(CO)/sub 6/ (2) with the organic bridge on diiron core in a complicated .mu.-(1,2,5-.eta./sup 3/:1,4,5-.eta. /sup 3/) fashion. The keto fragment in (2) comes presumably from the decomposition of (1) that liberates CO. However, stirring a THF mixture of (1) and PhC.ident.CPh under CO(g) at-60.degree.C for 3h then at room temperature overnight results in [ -C (O)CPh=CPhC(O)- ] Fe(CO)/sub 4/ (3), a compound not isolated in the earlier thermal or photochemical reactions of PhC.ident.CPh with ironcarbonyl. The X-ray structure determinations for both (2) and (3) have been performed.
