标题 :Synthesis of ruthenium or osmium metathesis catalysts
发明人：GRUBBS ROBERT H; BELDERRAIN TOMAS R; BROWN SETH N; WILHELM THOMAS E
权利人:CALIFORNIA INST OF TECHN
摘要:The present invention relates to the synthesis of highly active ruthenium and osmium carbene metathesis catalyst in good yield from readily available starting materials. The catalysts that may be synthesized are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are independently any anionic ligand; n L and L 1 are any neutral electron donor ligand; and, n R and R 1 are each hydrogen or one of the following substituent groups: C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, C 1 -C 20 alkyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl. Optionally, the substituent group may be substituted with one or more groups selected from C 1 -C 5 alkyl, halogen, C 1 -C 5 alkoxy, and aryl. When the substitute aryl group is phenyl, it may be further substituted with one or more groups selected from a halogen, a C 1 -C 5 alkyl, or a C 1 -C 5 alkoxy. Specific synthetic protocols for vinyl alkylidene catalysts wherein R is hydrogen and R 1 is —CHCR 12 R 13 and non-vinyl alkylidene catalysts are also disclosed. In addition to the ease of synthesis (typically a one-step synthesis), the reactions generally may be run at or above room temperature and the resulting products usually may be used without extensive post synthesis purification.

摘要:It relates to the field of synthetic macromolecular chemistry, and discloses a method for one-step synthesis of thiol-functionalized polyester polyols by organic catalysis. This method uses lactone monomer as reaction raw material, thiol-alcohol as initiator, and diphenyl phosphate as organic catalyst to catalyze and synthesize the thiol-functionalized polyester polyols. The present invention provides a method which is simple, inexpensive, easily controllable and environmentally friendly to prepare thiol-functionalized polyester polyols with the easily available and controllable catalyst. The method can selectively catalyze the ring opening polymerization of lactone to prepare thiol-functionalized polyester polyols using the organic catalyst.
