“…Diethyl arylphosphonates 2b–l were obtained in yields of 67–86% after column chromatography. From among the 12 products, 2a–c, 2f–h , and 2j,k have been described earlier whereas compounds 2d, 2e, 2i , and 2l are new. 31 P NMR and mass spectral data of the known phosphonates were compared with those reported in the literature.…”

“…The new species were fully characterized by 31 P, 13 C, and 1 H NMR, as well as HR mass spectral data. It is noteworthy that diethyl arylphosphonates 2a–c, 2f–h , and 2j,k were prepared earlier by the catalytic coupling reaction of aryl bromides and diethyl phosphite .…”

“…Derivate des Triphenylphosphans mit Phosphonatogruppierungen des Typs B [3] erwiesen sich als aktive Katalysatorliganden für Carbonylierungsreaktionen [3b], Telomerisationsreaktionen von 1,3-Dienen und Suzuki-Kupplungsreaktionen [16] in Zweiphasensystemen. Sie lassen sich an anorgani schen Trägermaterialien immobilisieren und so in aktive heterogene Katalysatorsysteme überführen [5,6,17].…”

Zu Ver gleichszwecken wurden die Phosphane Ph7P-C6H4-2-COOH (A) [2] und Ph2P-C6H4-3-P 02Na2 (A') [3] in die Untersuchungen einbezogen, um den Ef fekt der CH2-Spacergruppierung auf die katalyti sche Aktivität aufzuzeigen. Der Katalysator wurde separat durch Zugabe von acht Äquivalenten der je weiligen Phosphanliganden zu Palladium(II)-acetat in Ethylenglykol gebildet.…”
