Transition-Metal-Substituted Acyl Phosphanes and Phosphaalkenes. 32.1 Transformation of an FePC Unit of a Phosphaalkene into a FePCNNC Moiety by Chain Extension through Insertion of the 1,3-Dipole (-NN(Ar)CH+) of Sydnones
摘要:
The metallophosphaalkene (eta(5)-C5Me5)(CO)(2)FeP=C(NMe2)(2) (1) underwent reaction with sydnones 3-aryl-NNOC(O)CH (aryl = C6H5 (2a), 4-FC6H4 (2b), 4-ClC6H4 (2c), 4-BrC6H4 (2d)) to afford the novel ferriophosphaalkenes (eta(5)-C5Me5)(CO)(2)FeP=CHN(aryl)N=C(NMe2)(2) (3a-d). Compound 3a forms the [2 + 2] phosphetanyl cycloadduct 4a with dimethyl fumarate. The molecular structure of 3a was determined by single-crystal X-ray diffraction.
