text: Novel metalloreagent Cp(CO)2FeP(Se)(OR)2 produced from P-Se bond cleavage in the thermal reaction of [CpFe(CO)2]2 with phosphor-1,1-diselenolates.
  The reaction of [CpFe(CO)2]2 with NH4Se2P(OR)2 yields a novel reagent Cp(CO)2FeP(Se)(OR)2, which has demonstrated coordination properties at the Se center to form heterometallic clusters as well as reactivity at the Se site toward C-based electrophiles.
