Usage

General Description

[Tris(trimethylsilyl)]arsenide, also known as As[TMS]3, is an organoarsenic compound that is commonly used as a precursor for the synthesis of various arsenic-containing compounds. It is a colorless, flammable liquid with a strong, unpleasant odor and is highly reactive. As[TMS]3 is primarily used in chemical research and manufacturing processes, particularly in the production of specialty chemicals, pharmaceuticals, and electronic materials. It is known to react violently with water, air, and oxidizing agents, and therefore must be handled and stored with extreme caution. Due to its high reactivity and toxicity, As[TMS]3 is classified as a highly hazardous chemical and appropriate safety measures must be taken when working with this compound.

ORGANOMETALLARSINE. IX. t-BUTYL(TRIMETHYLELEMENT(IVB))ARSINE UND IHRE PENTACARBONYLCHROM-, -MOLEBDAEN- UND -WOLFRAM-KOMPLEXE

Di-t-butylchloroarsine reacts with t-butyllithium to give tri-t-butylarsine and with trimethylchlorosilane-magnesium-tetrahydrofuran under formation of di-t-butyl(trimethylsilyl)arsine.Tris(trimethylsilyl)arsine was obtained in a similar way from arsenic trichloride with trimethylchlorosilane-magnesium-HMPA.Trimethylsilylarsines react with trimethylchloro-germane and -stannane to give the corresponding trimethyl-germyl- and stannyl-arsines.Organometalarsines react with hexacarbonyl-chromium, -molybdenum, or -tungsten with formation of pentacarbonyl(organometalarsine)- chromium, -molybdenum, or -tungsten complexes.NMR, IR, Raman, and He(I)-PE data of the new bulky arsine ligands and of some complexes are reported.

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.
