Synthesis, structure reactivity of the arsaalkenes RAs=C(NMe2)2 [R = Me3Si, (η5-C5Me5)(CO)2Fe] and the 1,2-dihydroarsete (η5-C5Me5)(CO)2FeAs-C(NMe 2)=C(CO2Me)-CH(CO2Me)

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)2FeBr led to the formation of (η5-C5Me5)(CO)2-FeAs=C(NMe 2)2 (4). Reaction of the latter with dimethyl fumarate gave the 1,2-dihydroarsete (η5-C5Me5)(CO)2Fe-As-C(NMe 2)=C(CO2Me)-CH(CO2Me) (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. VCH Verlagsgesellschaft mbH, 1996.
