Notes:
Reaction of equimolar amounts of thiuronium salt [(Me2N)2C-SMe]I (1, with LiAs(SiMe3)2 · 2 THF (2) afforded arsaalkene Me3SiAs=C(NMe2)2 (3). Combination of 3 with (η5-C5Me5)(CO)2 FeBr led to the formation of (η5-C5Me5)(CO)2-FeAs=C(NMe2)2 (4). Reaction of the latter with dimethyl fumarate gave the 1,2-dihydroarsete (η5-C5Me5)(CO)2-Fe (6). Compounds 3, 4, and 6 were characterized by means of spectroscopy (IR, 1H, 13C{1H}, 29Si{1H} NMR and mass spectrometry). The molecular structures of 4 and 6 were determined by X-ray diffraction analysis.
