Komplexe Quecksilber‐Verbindungen aus Äthylen und Kohlenoxyd

The Addition Compounds of Olefins with Mercuric Salts.

“…This reaction gives a 97 per cent yield of crude product and an 85 per cent yield of pure material (54). The higher alcohols behave similarly but the reaction is slower (29,54).…”

“…Many unsaturated compounds were added to mercuric salts, amongst which unsaturated alcohols and esters were the most fruitful subjects of research. In 1914 Schoeller, Schrauth, and Essers (54) showed that in general the solvent played an essential part in the addition and that mercuric salts in alcoholic solution reacted with olefins to produce the corresponding alkyl ethers of the compounds of series I. More recently (1929 and 1945) it has been found that in glacial acetic acid, mercuric acetate yields the acetyl derivatives (30),…”

Addition of cycloheptatrienylidene to cis- and trans-1,3-pentadiene and to styrene. Rearrangement of spiro[2.6]nona-4,6,8-trienes

“…By comparison of the spectral properties of this mixture with the mixture derived from the trans diene, the following spectral properties of 3b were inferred. 3b: nmr (CDC13) 1.11 (d, J= 6.5 Hz, methyl), 1.6 (m, Hg), 2.5 (m, Hs), 2.94 (m, methylene), 5.01 (d of d, J = 6 and 9 Hz, He), 5.7-6.2 (m, H2, Hg, Hg, H10), 6.54 (asym t, H3, H4); ir (neat) essentially same as 3a; mass spectrum m/e (rel intensity) 158 (50), 143 (100), 129 (68), 128 (91), 115 (42). Oxidation precluded a satisfactory elemental analysis.…”

“…8-Phenylbicyclo [5.4.0]nona-l,3,5-triene (6). Heating a sealed, degassed nmr solution of 5 in CDCF/TMS at 75°resulted in the conversion of 5 to 6.…”

Reaction of cupric alkoxide and carbon monoxide

“…Ac0HgC02CH3 + q® -0NCO.CH3 + Hg + AcOH (7) The Cu(OCH3)2-CO and Cu(acac)(OCH3)-CO systems have been used as initiators of free-radical polymerization. 10 The active species are the reduced cuprous compounds of Cu(OCH3) and Cu(acac), which undergo homolytic fission to produce methoxyl and acetylacetonyl radicals, respectively.…”
