  • Publication number: 20040002612
    Abstract: A fluorine-containing styrene monomer of the formula (2) is produced by a first, second or third process. The first process includes (a) reacting a compound of the formula (1) with a compound of the formula (3), in the presence of a metal catalyst; (b) reacting the product of the step (a) with a base; and (c) reacting the product of the step (b) with hydrogen, in the presence of a metal catalyst and a phosphine or amine, thereby producing the target styrene monomer. The second process includes reacting a compound of the formula (1) with a compound of the formula (12), in the presence of a metal catalyst, thereby producing the target styrene monomer. The third process includes reacting a compound of the formula (13) with a compound of the formula (14) or (15), in the presence of a base, thereby producing the target styrene monomer.

  • Patent number: 6573395
    Abstract: A process for the enantioselective reduction of prochiral ketones to chiral alcohols by (a) the reaction of a prochiral ketone with a silane agent, which is present in a stoichiometric quantity, in the presence of a catalyst derived from a Zn, Co or Cd precursor compound and from a chiral amine, imine, alcohol or amino alcohol ligand; (b) the hydrolysis of the siloxane obtained using an appropriate agent; and (c) the separation and purification of the optically active alcohol formed. Polymethylhydrosiloxane (PMHS) is a preferred silane agent, zinc is a preferred metal, and the precursor compound is produced by reacting a salt or complex of the respective metal with the reducing agent. In another embodiment, an appropriate salt of the chosen metal is used directly in the reaction with the chiral ligand to produce the catalytic form after reaction with the ligand. The process enables high enantiomeric excesses (ee) to be obtained in chiral alcohols.
