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

Article abstract of DOI:10.1016/S0022-328X(00)89149-4

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.
