  • Patent number: 4175187
    Abstract: Tertiary allylic amines are obtained from vinylic halides and olefins, and substituted derivatives thereof, by reacting said halide with a mono-, di-, or tri-substituted olefin and an unhindered basic secondary amine in the presence of a palladium catalyst.
    Type: Grant
    Filed: October 24, 1978
    Date of Patent: November 20, 1979
    Assignee: University of Delaware
    Inventor: Richard F. Heck
  • Patent number: 4128554
    Abstract: Carboxylic acid amides are obtained from aryl, heterocyclic, and vinylic halides and substituted derivates thereof, by reacting same with a primary or secondary amine and carbon monoxide, in the presence of a palladium catalyst and if necessry a tertiary amine at about 20.degree.-150.degree. C and from at least a half atmosphere pressure.
    Type: Grant
    Filed: March 10, 1977
    Date of Patent: December 5, 1978
    Assignee: University of Delaware
    Inventor: Richard F. Heck
  • Patent number: 3988358
    Abstract: Carboxylic acid esters or amides are obtained from aryl, heterocyclic, vinylic, ethynylic, and benzylic halides and substituted derivates thereof, by reacting same with an alcohol or primary or secondary amine and carbon monoxide, in the presence of a palladium catalyst and if necessary a tertiary amine at about 20.degree.-150.degree. C and from about a half to about 100 atmospheres pressure. A typical example is the conversion of bromobenzene into n-butyl benzoate at 100.degree. C and one atmosphere of carbon monoxide in the presence of tri-n-butyl-amine and a catalytic amount of PdBr.sub.2 [P(C.sub.6 H.sub.5).sub.3 ].sub.2.
    Type: Grant
    Filed: May 10, 1974
    Date of Patent: October 26, 1976
    Assignee: The University of Delaware
    Inventor: Richard F. Heck
  • Patent number: 3960932
    Abstract: Aldehydes are obtained from aryl, vinylic and heterocyclic halides and substituted derivatives thereof, a tertiary amine, carbon monoxide and hydrogen at from about 50.degree.-175.degree.C under from about one to 200 atmospheres pressure and with PdX.sub.2 [P(C.sub.6 H.sub.5).sub.3 ].sub.1 or 2 as a catalyst where X is acetate or a halogen. The ratios of carbon monoxide to hydrogen are not critical but the most favorable reactions are usually obtained with ratio from about 0.1 to about 10. A typical example is the conversion of p-bromoanisole to anisaldehyde in 84% yield at 150.degree.C in 18 hrs. at 1000 psig. of 1:1 CO to H.sub.2 with one mole percent of PdBr.sub.2 [P(C.sub.6 H.sub.5).sub.3 ].sub.2 as catalyst and with tri-n-butylamine as the tertiary amine.
