Reaktionen von Organobleiderivaten mit Schwefelverbindungen. III. Die Umsetzung von Tetraäthyl‐ und Tetramethylblei mit Schwefeldioxid

Abstract: Tetraäthylblei reagiert in inerten Lösungsmitteln mit trockenem Schwefeldioxid über die Stufe des Triäthylbleiäthansulfinats zu Diäthylblei‐bis‐(äthansulfinat). Beide Äthylbleisalze disproportionieren bei der Wasserdampfdestillation, langsamer auch beim Aufbewahren, zu Tetraäthylblei. Bleiäthansulfinat und Diäthylsulfon, wie durch spektrophotometrische Konzentrationsbestimmung der farbigen Äthylblei‐Dithizon‐Komplexe nachgewiesen wird. Die Sulfinierung von Tetramethylblei verläuft zögernder und wird stärker vo… Show more

“…The cleavage of alkyl-metal bonds by sulfur dioxide has been demonstrated for a variety of different systems (1)(2)(3). In some cases, the sulfone is formed; thus, Hartman and Wojcicki (I) have shown that CH3Mn(C0)5 gives CH3-S02Mn(C0)5.…”

“…In a rigid matrix vibrational relaxation of this species to a level from which isoenergetic crossing to the 3 8potential surface could occur is undoubtedly a relatively slow process. Therefore the employed7 delay times of 30-200 /usee between flash and analysis lamp are adequate for observation of the initially formed Recently there has been considerable interest in complexes of metals with sulfinate ions,1-10 and especially in the structures of sulfinato complexes formed by sulfur dioxide insertion into metal-carbon bonds.113i 4,7,8…”
