Iron carbonyl derivatives shift

The Dewar-benzene iron carbonyl derivative [97], like perfluorobicyclo[2,2,0]hexa-2,5-diene itself, undergoes Diels-Alder addition to give [98a and b], with the chemical shifts shown. (53) [98a] is also formed, although in low yield, by the reaction of the preformed Diels-Alder adduct [99] with Na[(7r-C5H5)Fe(CO)2], confirming the stereochemistry of the addition. 

Several interesting and significant papers concerning ligated CO appeared in 1985. Quantitative aspects of the reaction of OH" and OMe" with M(C0)s and M3(C0)i2 (M = Fe, Ru or Os) have been reported and the implications with regard to the water gas shift reaction were noted.A full account of a method for computing the most favourable initial site for nucleophilic attack on a transition metal complex has been described and applied to reactions of cationic iron carbonyl derivatives. Nucleophilic attack by H2O, OH" and H" on dicationic Ir carbonyl complexes yields cationic hydroxycarbonyl and formyl...
