标 题 :Rhodium based catalysts for the synthesis of 1,4-dienes
发明人：SU A
权利人:DU PONT
摘要:Improved catalysts are provided for the synthesis of 1,4-dienes from Alpha -monoolefins and conjugated dienes. The catalysts are rhodium (III) salts in combination with amides, phosphoramides, phosphine oxides, or water. The improved catalysts allow control of the trans-cis ratio of the 1,4-diene formed and are operable at useful rates in a wide range of solvent systems, both protonic and aprotic.

摘要:A process for the purification of tertiary phosphine oxides obtained in a Wittig synthesis as a contaminated by product resulting from the reaction of the corresponding tertiary phosphines, especially triphenylphosphine. The contaminated tertiary phosphine oxides coming from this Wittig synthesis have the formula I ##STR1## in which R 1 , R 2 , and R 3 denote C 1 -C 12 alkyl, C 5 -G 8 cycloalkyl, aryl, C 7 -C 20 aralkyl, or C 7 -C 20 alkylaryl. The contaminated phosphine oxide I or phosphine oxide I-containing mixtures, optionally in an inert solvent, are first caused to react with an inorganic or organic acid at temperatures of from 0° to 150° C. to form a crystallized acid salt. The resulting salt crystals are then treated in a purifying step with water or an inorganic base or an organic base to again form the tertiary phosphine oxide. This reformed oxide is then extracted with an inert organic solvent from which the purified tertiary phosphine oxide is finally liberated.

摘要:A catalyst composition for organic a symmetric synthesis is provided, which comprises: n (A) a lanthanoid element ion; n (B) a binaphthol, and n (C) a nitrogen and/or phosphorus compound such as lutidine-N-oxide, 1,3-dimethyl-2-imidazolldinone, hexamethyl-phosphortriamide, triphenylphosphine oxide, tri(2-methylphenyl)phosphine oxide or tri(4-methylphenyl )phosphine oxide. Asymmetric epoxidation of an enone is conducted by allowing an enone to react with an oxidizing agent in the presence of the catalyst composition or a catalyst solution containing the catalyst composition.
