✦ Synopsis
We have reported recently on the synthesis and reactivity of d6 and dX metal carbonyl complexes of 7,7-dimethoxy-5,6-dimethylidenebicyclo[2.2.l]hept-Zene [I]. Among the 30 compounds reported in [l], we have now unambiguous indication that the iron complex 1 and the ruthenium complex 2, originally formulated as [M(CO),(q2olefin)] complexes, are in fact [M(CO),(q' : 0-a-olefin)] complexes as indicated in the Formulae. These are uncommon examples of d8 metal carbonyl complexes bearing an 1 M=Fe(CO), 2 M=Ru(CO), 3 M=Cr(CO), 4 M = Mo(CO), 5 M=W(CO),
