Transformation of dimetallacyclopentanes into beta-substituted enamine-, alkylidene-, and alpha,beta-unsaturated acyl-bridged diiron complexes

Journal article

Nucleophilic addition of primary amines RNH2 to Cβ of the diiron allenyl complex [Fe2-(CO)6(μ-PPh2){μ-η 1:η2(H)C=C=CH2}] (1) affords the zwitterionic dimetallacyclopentane derivatives [Fe2(CO)6(μ-PPh2){μ-η 1:η1-H2C-C(NHR)-CH2}] (R = Pri (2a), CH2Ph (2b), CeH11 (2c), Prn (2d)). In refluxing toluene, 2a-d rearrange to give the nitrogen-coordinated organodiiron α,β-unsaturated amines [Fe2(CO)5(μ-PPh2){μ-η 1(C):η2(C):η1(N)-(H)C=CCH 3-(NHR)}] (R = Pri (3a), CH2Ph (3b), C6H11 (3c), Prn (3d)) via lo...
