Abstract
Reaction of 3 equiv. of 2-trimethylsiloxyphenyl isocyanide 1 with (η5-C5H5)Fe(CO)2Cl yields the triisocyanide complex [(η5-C5H5)Fe(1)3]Cl 5; hydrolysis of the Si–O bonds in 5 leads to intramolecular nucleophilic attack of the hydroxy oxygen atoms at the isocyanide carbon atoms and formation of {(η5-C5H5)Fe[[graphic omitted])][[graphic omitted])](CNC6H4-2-OH)}6, a complex which was shown by X-ray crystallography to contain a 2-hydroxyphenyl isocyanide, a benzoxazol-2-yl and a 1,2-dihydrobenzoxazol-2-ylidene ligand.Keywords
