The metallophosphaalkene (η5-C5Me5)(CO)2FeP=C(NMe 2)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 (η5-C5Me5)(CO) 2FeP=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.
