Ammonium-tagged ruthenium-based catalysts for olefin metathesis in aqueous media under ultrasound and microwave irradiation

The influence of microwave and ultrasonic irradiation on the performance of ammonium-tagged Ru-based catalysts in olefin metathesis transformations in aqueous media was studied. Differences in the catalytic activity in correlation with the nature of the present counter ion and the size of the N-heterocyclic carbene (NHC) ligand were revealed. The presented methodology allows for preparation of a variety of polar and non-polar metathesis products under environmentally friendly conditions.

Factors relevant for the regioselective cyclopolymerization of 1,6-heptadiynes, N,N-dipropargylamines, N,N-dipropargylammonium salts, and dipropargyl ethers by RuIV-alkylidene-based metathesis initiators

The factors relevant for the regioselectivity of insertion of various 1,6-heptadiynes, N,N- dipropargylamines, N,N-dipropargylammonium salts anddipropargyl ethers into different RuIV-alkylidenes, i.e., [R u(CF 3COO)2(IMesH2)(=CHR), (R = 2,4,5-(MeO) 3-C6H2(l1) 2-(2-PrO)-5-NO2-C 6H3 (I3), 2-(2- PrO)-C6H4 (I4)), [Ru(CF3COO)2(1,3-dimesityl-3,4,5,6-tetrahydropyrimidin-2- ylidene)(=CH-2-(2-PrO)-5- NO2-C6H3)] (I2), [Ru(CF3COO)2(3-mesityl-1-((1?fl)-1?- phenylethyl)-imidazolin-2-ylidene)(=CH-2-(2-PrO)- C6H4)] (I5) and [Ru(C6F5COO)2(IMesH 2)(=CH-2-(2-PrO)-C6H4)] (I6), (IMesH 2 = 1,3-dimesitylimidazolin-2- ylidene), is described. 13C NMR experiments revealed that all polymers synthesized by the action of I1-I6 consisted virtually solely (>95percent) of five-membered repeat units, i.e., (cyclopent-1-enylene)-1,2-vinylenes, 3,4-(1 H-2,5-dihydropyrrylenium)-3,4- vinylenes, and (2-pentyl-2,5-dihydrofurylene)-3,4-vinylenes, respectively. The 13C NMR-based assignments were supported by the synthesis of model compounds, i.e., (cyclopent- 3-ene-1,1-diyldimethylbis(tris(3,5-dimethoxyphenyl) carboxylate) (MC1) and N-propyl-N-ethyl-2,5-dihydro- pyrrolium tetrafluoroborate (MC2), as well as by ene-yne cross metathesis reactions of 3-(propargyloxy)- 1-octyne (M6) with trimethylallylsilane. In the polymerization of N-ethyl-N,N-dipropargylamine (M9), an intermediate was isolated that shedslight onto the role of heteroatoms in the 4-position of 1,6-heptadiynes in cyclopolymerization. In addition, in the cyclopolymerization of M9 b y I4 the product resulting from backbiting has been isolated and explains for the low polymerization propensity of Ru-alkylidenes for N-alkyl-N,N-dipropargylamines.

Facile synthesis of effcient and selective ruthenium olefin metathesis catalysts with sulfonate and phosphate ligands

A series of novel, air-stable ruthenium NHC catalysts with sulfonate and phosphate anions have been prepared easily in one pot at high yields using commercially available precursors. The catalysts were found to be effective for ring-opening metathesis polymerization, ring-closing metathesis, and cross-metathesis. The catalysts showed higher cis-selectivity in olefin cross-metathesis reactions as compared to earlier known ruthenium-based olefin metathesis catalysts, with allylbenzene and cis-1,4-diacetoxybutene as substrates.
