The diazotization of primary aromatic amines with a strongly electrophilic mononitrosyl complex, [Ru(NO)(NO2)L2](ClO4)2 [L = 2-(phenylazo)pyridine], in acetonitrile and dichloromethane, is described. The reactions were studied by following the reaction sequence through the isolation of products at various stages of each reaction.

Tricarbonyl[(1−4-η)-2-methoxy-5-methylenecyclohexa-1,3-diene]iron reacts with electrophiles to give the cyclohexadienylium−Fe(CO)3 cation, which either reacts with nucleophiles to form a new quaternary center or undergoes competitive loss of an acidic α-proton to give a new triene complex. This constitutes a new reaction sequence for the synthesis of 4,4-disubstituted cyclohexen-2-ones with the simultaneous
