Abstract The one‐bond nucleophilic reactivities of seven cyclic α‐diazo carbonyl compounds in dichloromethane were determined by analyzing the kinetics their reactions with benzhydrylium ions (one‐bond reference electrophiles) at 20 °C according to Mayr‐Patz equation. Though not calibrated for pericyclic reactions, identified nucleophilicities also reflect relative 1,3‐dipolar cycloadditions di...
Dinuclear iron carbonyl complex 2, which contains an elongated unsupported Fe-Fe bond, was synthesized by the reaction between Fe2(CO)9 and phosphinyl radical 1. Thermal Fe-Fe bond homolysis led to the generation of a four-coordinate carbonyl-based iron-centered radical, 3, which is stabilized by π-donation. Complex 3 exhibited high reactivity toward organic radicals to form diamagnetic five-co...
