The mild pyrolysis of polyolefins, including high-density polyethylene (HDPE), results in pyrolysis oils containing long-chain olefins as major products. In this paper, novel bicyclic (alkyl)(amino)carbene ruthenium (BICAAC-Ru) temperature-activated latent olefin metathesis catalysts, which can be used for catalytic decomposition of long-chain olefins to propylene are reported. These thermally stable catalysts show significantly higher selectivity to propylene at a reaction temperature of 75 degrees C compared to second generation Hoveyda-Grubbs or CAAC-Ru catalysts under ethenolysis conditions. The conversion of long-chain olefins (e.g., 1-octadecene or methyl oleate) to propylene via isomerization-metathesis is performed by using a (RuHCl)(CO)(PPh3)(3) isomerization co-catalyst. The reactions can be carried out at a BICAAC-Ru catalyst loading as low as 1 ppm at elevated reaction temperature (75 degrees C). The observed turnover number and turnover frequency are as high as 55 000 and 10 000 mol(propylene) mol(catalyst)(-1) h(-1), respectively.}, keywords = {MECHANISM; ETHYLENE; Propylene; cracking; metathesis; propene; STABLE CARBENES; BEARING; RUTHENIUM COMPLEXES; 1-Butene; BICAAC; Hydrocarbon Decomposition; ISOMET}, year = {2022}, eissn = {1521-3773}, orcid-numbers = {Hancsók, Jenő/0000-0003-1959-7604; Valyon, József/0000-0002-3608-060X} } @article{MTMT:32687686, title = {Synthesis and characterization of novel PEPPSI type bicyclic (alkyl)(amino)carbene (BICAAC)-Pd complexes}, url = {https://m2.mtmt.hu/api/publication/32687686}, author = {Nagyházi, Márton and Almási, Balázs and Lukács, Ádám and Bényei, Attila Csaba and Nagy, Tibor and Kéki, Sándor and Tuba, Róbert}, doi = {10.1016/j.molstruc.2022.132483}, journal-iso = {J MOL STRUCT}, journal = {JOURNAL OF MOLECULAR STRUCTURE}, volume = {1256}, unique-id = {32687686}, issn = {0022-2860}, abstract = {A series of bicyclic alkylamino carbenes (BICAAC) (where N-aryl = dipp, mes, 2,6-dimethyl-4-(dimethylamino)phenyl, 5a–d) and their novel air- and moisture-resistant pyridine (pyridine, 4-dimethylaminopyridine) containing palladium Pd(II) complexes (6a–e) were synthetized and characterized. As novel examples of the PEPPSI (“pyridine enhanced precatalyst preparation stabilization and initiation”)-Pd compounds, the reported complexes have shown high activity in Mizoroki–Heck coupling reaction even at as low as 100 ppm loading (TON up to 10000).
