  • Process for the preparation of ketones
    Patent number: 5274136
    Abstract: An improved method for the decarbalkoxylation of alkylated .beta.-keto esters to obtain high yields of ketones. In accordance with the method, decarbalkoxylation of alkylated .beta.-keto esters is accomplished by heating the esters in the presence of dilute aqueous alkali and an effective amount of a phase-transfer agent. The method produces commercially practical yields of ketone in a manner which is facile, economical and environmentally safe. Novel methylene-linked pyrethroid ketones produced from the improved method exhibit insecticidal activity against various agricultural pests.
    Type: Grant
    Filed: July 1, 1992
    Date of Patent: December 28, 1993
    Assignee: The United States of America as represented by the Secretary of Agriculture
