Abstract
Allylic compounds are carbon-to-carbon coupled to substituted olefins by contacting the two compounds in the presence of a catalyst system comprising a Group VIII metal component, a bromine or iodine component, and a Group VA component. The foregoing catalytic process also promotes the intra-molecular, carbon-carbon coupling of allylic and substituted olefin groups wherein both processes provide a method for producing sorbates and related compounds.
Claims19
A catalytic process for carbon to carbon coupling of allylic compounds with substituted olefins, comprising:
- contacting allylic compounds having the formula ##EQU11## where R, R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are each independently hydrogen, or a hydrocarbyl radical, and Z is hydrogen, chlorine, an alcohol, or --OR group with R having a hydrocarbyl radical;
- and
- substituted olefins having the formula ##EQU12## where R and R.sup.1 are each independently hydrogen or a hydrocarbyl radical and Y is one of ##EQU13## with R being a hydrocarbyl radical;
- said contacting occurring in the presence of a catalyst system comprised of a a Group VIII metal component, at least one of a bromine or iodine component, and Group VA component.
A catalytic process for intramolecular, carbon-to-carbon coupling of allylic and substituted olefin groups wherein both groups are contained in the same compound comprising:
- contacting the compound with a catalyst system comprised of a Group VIII metal component, at least one of a bromine or iodine component, and a Group V A component.
A catalytic process for producing compounds having a pentadienyl radical selected from the group consisting of:
- R.sub.7 [ C= C--C--C= C -- Y ] (a)
- R.sub.7 [C -- C = C-- C = C -- Y] (b)
- R.sub.7 [ C = C -- C = C -- C -- Y ] (b) where Y is ##EQU14## and R is at least one of hydrogen, or an alkyl or alkenyl radical having from 1 to about 20 carbon atoms per molecule:
- comprising contacting allylic compounds with substituted olefins in the presence of a catalyst system comprised of a Group VIII metal component, at least one of bromine or iodine component, and a Group V A component.
