标题 :Synthesis of ruthenium or osmium metathesis catalysts

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.

标题 :Synthesis of a triangulene ring system and derivatives thereof

摘要:A three step synthesis of the 8,12-dihydro-4H-dibenzo[cd,mn]pyren-3a 2 -ylium cation (triangulenium cation) is effected by cascade cyclization of a tetra-benzyl alcohol precursor in triflic acid solution. This cation is easily observed by NMR and optical spectroscopy. Quenching of the cation into basic solutions or by hydride transfer from triethylsilane provides access to stable dihydro and tetrahydro[3]triangulenes. This route makes several [3]triangulene precursors more readily available for development of new applications in the field of molecular electronics.
