权利人:BRITISH PETROLEUM CO PLC
摘要:A process for preparing a chiral carboxylic acid or ester thereof, either as a single enantiomer or as a mixture of enantiomers in which the presence of one enantiomer is enhanced relative to the others comprises reacting a prochiral olefinic function and either water or an alcoholic function with carbon monoxide in the presence of a protonic acid other than nitric acid, a single enantiomer of an optically active compound chosen from the class of chiral phosphoric acids or derivatives thereof, and a catalyst comprising (a) at least one of the metals palladium, rhodium, ruthenium, iridium and cobalt and (b) copper. A preferred class of optically active compounds comprises either the (S+) or the (R-) enantiomer of 2,21-(1,11-Binaphthyl) phosphoric acid or its esters or its salts, optionally substituted.

摘要:Personal care compositions, such as oral care and skin care compositions containing a flavor/perfume system comprising one or more coolants. The pleasant cool sensation provided by a coolant is enhanced in terms of quicker onset, greater intensity, impact or longer duration, which improves appeal and acceptability of the compositions to consumers.

标 题:Use of metal-accumulating plants for implementing chemical reactions
发明人：GRISON CLAUDE; ESCARRE JOSE
权利人:CENTRE NAT RECH SCIENT; UNIV MONTPELLIER 2 SCIENCES ET TECHNIQUES
摘要:A method of implementing organic synthesis reactions uses a composition containing a metal catalyst originating from a calcined plant. The plants can be from the Brassicaceae, Sapotaceae and Convolvulaceae family, and the metal catalyst contains metal in the M(II) form such as zinc, nickel, manganese, lead, cadmium, calcium, magnesium or copper. Examples of the organic synthesis reactions include halogenations, electrophilic reactions, cycloadditions, transesterification reactions and coupling reactions, among others.
