Official abstract text for this publication.
Provided herein are compounds prepared from processes that include ethyleneolysis. Exemplary processes include the preparation of terminally-unsaturated fatty acid reactant by ethyleneolysis catalyzed by a cyclic alkyl amino carbene ruthenium complex. The subsequent oligomerization of terminally-unsaturated fatty acid reatants provides estolide compounds, as exemplified by the process set forth below:
Opening claim text (preview).
1 - 201 . (canceled) 202 . A process comprising providing a terminally-unsaturated fatty acid reactant derived from a process that includes contacting one or more unsaturated fatty acid substrates having at least one internal site of unsaturation with a cyclic alkyl amino carbene ruthenium complex in the presence of ethylene; and reacting the terminally-unsaturated fatty acid reactant with a second fatty acid reactant to provide at least one compound. 203 . (canceled) 204 . (canceled) 205 . (canceled) 206 . The process according to claim 202 , wherein the one or more unsaturated fatty acid substrate comprises a triglyceride having at least one oleic acid residue. 207 . (canceled) 208 . (canceled) 209 . The process according to claim 202 , wherein the terminally-unsaturated fatty acid reactant comprises 9-decenoic acid. 210 . The process according to claim 202 , wherein the second fatty acid reactant comprises at least one of a saturated fatty acid or an unsaturated fatty acid. 211 . (canceled) 212 . (canceled) 213 . The process according to claim 202 , further comprising esterifying the at least one compound with an alcohol to provide an esterified compound. 214 . The process according to claim 213 , further comprising hydrogenating the esterified compound to provide a hydrogenated compound. 215 . (canceled) 216 . (canceled) 217 . (canceled) 218 . (canceled) 219 . (canceled) 220 . (canceled) 221 . (canceled) 222 . The process according to claim 202 , wherein the cyclic alkyl amino carbene ruthenium complex comprises at least one compound selected from Formula B: wherein X 1 and X 2 are independently selected from alkoxy and halogen; R 6 , R 7 and R 8 are independently selected from branched or unbranched alkyl; R 5 is selected from branched or unbranched alkyl, optionally substituted aryl, optionally substituted heteroaryl, optionally substituted arylalkyl, and optionally substituted heteroarylalkyl, or R 5 and R 6 are taken together with the carbon to which they are bound to form a 5-, 6-, or 10-membered cycloalkyl or heterocyclyl ring, each of which is optionally substituted; R 12 is a branched or unbranched alkyl; R 9 and R 11 are independently selected from hydrogen and branched or unbranched alkyl; and R 10 is branched or unbranched alkyl. 223 . (canceled) 224 . The process according to claim 222 , wherein when R 11 is hydrogen, R 9 comprises a smaller number of atoms than R 10 . 225 . The process according to claim 222 , wherein when R 11 is hydrogen, R 9 is selected from unbranched alkyl and R 10 is selected from branched alkyl. 226 . The process according to claim 222 , wherein X 1 and X 2 are halogen. 227 . The process according to claim 226 , wherein X 1 and X 2 are chlorine. 228 . The process according to claim 222 , wherein R 12 is a branched C 3 to C 10 alkyl. 229 . The process according to claim 228 , wherein R 12 is isopropyl. 230 . (canceled) 231 . The process according to claim 222 , wherein R 6 , R 7 and R 8 are independently selected from methyl, ethyl, and propyl. 232 . (canceled) 233 . (canceled) 234 . The process according claim 222 , wherein R 11 is hydrogen. 235 . (canceled) 236 . The process according to claim 222 , wherein R 9 is selected from unbranched C 1 to C 10 alkyl. 237 . The process according to claim 236 wherein R 9 is selected from methyl, ethyl, and propyl. 238 . The process according to claim 222 wherein R 10 is selected from branched C 3 to C 10 alkyl. 239 . The process according to claim 238 , wherein R 10 is selected from isopropyl, isobutyl, and tert-butyl. 240 . The process according to claim 222 , wherein R 5 is aryl. 241 .
