Organomercury compounds as synthetic intermediates. Coupling of arylmercuric salts

A new organomercury(II) compound derived from both 3-ferrocenyl-2-crotonic acid and its decarboxylation product

“…The bond lengths of Hg-O and Hg-C are 2.127(3) Å and 2.022(6) Å, respectively. The Hg-O distance is close to that of these reported organomercury(II) compounds, [C(HgSO 4 ) 2 (HgOH 2 ) 2 ] (Hg-O: 2.131(11) or 2.12 (2) (7) Å) [17e]. The bond distance of Hg-C is expected and rather short, and is consistent with that of these previous compounds [6].…”

“…There has been considerable interest in the preparation and structure of organomercury(II) in recent years, mainly due to their application in the fields of catalysis [1], organic chemistry [2] and analysis chemistry [3], biochemistry [4] and organometallic synthesis [5]. In 1985, Lobana has reviewed the coordination chemistry of organomercury(II) involving phenanthrolines, bipyridines, tertiary phosphines/arsines and some related ligands [6].…”

“…Avec le bromhydrate de triphknyl phosphine, l'alcool hydroxy-2 mCthoxy-5 benzylique 6 donne du bromure d'hydroxy-2 mbthoxy-5 benzyl triphinyl phosphonium 7 [7]. Celui-ci est transform6 par les chlorures d'acides mCthoxy-5 ou mbthoxyd benzofuranne carboxyliques en esters 8a et 8b dont I'hCtCrocyclisation au moyen de [9] en traitant par le cuivre, en prCsence de chlorure de palladium, dans la pyridine, un dCrivC chloromercuriel en 2 du benzofuranne. Celui-ci est obtenu, comme cela a CtC fait a partir d'acides furoi'ques [10,11], par dCcarboxylation en solution sodique d'un acide benzofuranne carboxylique-2 en prCsence de chlorure mercurique.…”
