Reactivities of Secondary Phosphine Selenides Cp(CO)2FeP(Se)(OR)2: Formation of a Diiodine Charge Transfer Adduct and Se-Methylation
2009
The organoiron-substituted phosphine selenides Cp(CO)2FeP(Se)(OR)2 (R = iPr (1a), nPr (1b), Et (1c)) were synthesized. The metalloligands, capable of reacting as nucleophiles toward Me3OBF4, formed Se-methylated products (2a−c). Upon reaction with diiodine, they formed spokelike charge-transfer adducts (3a−c). Among them 1b, 2b, and 3a were structurally authenticated, and 3a was the first structurally characterized, charge-transfer spoke adduct of a secondary phosphine selenide with diiodine.
